It's not about measuring diverse data from the environment, which Tesla can do within the limits of its optical systems. It's about developing algorithms and using machine learning to handle a world of almost unlimited edge cases (what you called chaos). It's an extremely difficult problem to tackle, and the expert consensus today is we're still far from Level 5 autonomy. Waymo has proven you can get an 80% solution, but the problem is the remaining 20%. This ratio understates the actual difficulty, because covering the last 20% may require techniques that haven't been discovered yet.
Yea, that is the problem I see with autonomous driving in ultra crowded or bad weather conditions. There is an almost infinite number of possible configurations of say a road with snow, wet patches, dry spots, piles of plowed snow, all while the lane markers are covered over. And the conditions would be different for every snow incident and even at various time during the same storm (i.e. before plowing, after plowing, when melting starts, etc). Seems a daunting task indeed to program the AI to recognize all these conditions and react appropriately.

Tesla's AP is still learning. It has the best inputs/db to learn from and growing. Think of this as a 'kid' now. Eventually, it'll grow beyond any human capability.

It is not in any official stage yet, obviously, but it will get there.

Bad analogy and far from how machine learning works and behaves. It’s not magic lol.

Autopilot comes standard. I assume you bought FSD and regret paying $6-7K extra for that. Yeah, I wouldn't buy FSD in its current state. I'm hoping by the time Cybertruck comes out FSD will be good enough and worth it.

Sorry, meant FSD.

I probably worded my response poorly and I do agree with what you are saying.

Overall, I feel that until a good number of cars on the road have self driving capabilities, it's going to take a lot of brute force computation. It's a catch 22 where the more level 5 cars on the road, the easier it will be for cars to drive in unison but it takes a lot of people investing in technology that's not there yet in order to get there.

I'm still really curious about how they plan on doing FSD with no Lidar, especially in the rain & snow. In theory, the physics calculations should be even better in the snow than human driving, especially for recovery in a spin or a slide, but who knows...it's all vaporware until it happens. I'm a huge, huge fan of Tesla & really love the concept of Autopilot, but tbh it feels like a really nice party trick right now. When I test-drove Kia's Stinger, the lane-centering technology coupled with the TACC was actually really fantastic...and, I mean, if you do a lot of highway driving, that or EyeSight pretty much fits the bill for the majority of highway driving.

It really comes down to how they can interpret the data that they're given. To be honest, I'm leaning toward a bit of over-selling on the part of Tesla. It sort of feels like that uneasiness that I get listening to Peter Molyneux talk about a game. I just have to take everything with a hefty grain of salt, and a dash of "we'll see...".

With that said, I still really like the Y. Really fun to drive, roomy, lots of cool features. Downside is fully-loaded, in my state, after taxes, it's $78k with everything. With zero down, that's $1,300 a month on a 60-month loan. That's an awful lot for what is basically an electric Nissan Versa lol. That's like a mortgage payment, haha! And that's why a $40k-base Cybertruck sounds so good!

On a recent Rich Rebuilds video, he was talking about aftermarket upgrades for the Model 3 that unlock more power for the Dual Motor (i.e. non-Performance) AWD models. They tested an unlocked AWD vehicle against a Performance Model 3, and the unlocked vehicle was as fast as if not slightly faster than the Performance version. I guess what I'm trying to get at is that you could potentially go with a non-Performance Model Y and eventually get an upgrade. The only thing I'd worry about is how persnickety Tesla would be about the upgrades. Would they do something like disable Supercharging if they determine that your car has been modified?

The more I try to use Autopilot, the more I regret paying for it. The only FSD feature that I use is the auto lane change since the Y lacks basic blind spot monitoring in the mirrors.

Hm, that is a good point. I wish they would've added a real blind spot indicator on the Model Y rather than continuing with the awkward red vehicle function on the display. It just comes across as a bit hackneyed due to needing to keep your eyes on the road and not down at your screen. Ultimately, the Model 3 and Model Y really just need a simple HUD for the driver. I think if it had speed information and a MFD similar to what Ford uses, it would work fine. Ford's right screen can be swapped between things like Multimedia, which displays the current song, or Navigation, which displays the next turn information.

To your point, the nuances of driving are not something that the car can accurately measure. Maybe if the majority of cars were self driving and the roads where monitored in real-time, but a couple 100k cars trying to make it in chaos isn't realistic. I can't imagine it in a city when you throw in pedestrians, people on bikes and the random jackassery of people.

One thing that came to mind is just a sort of intuition that you have when driving. For example, you said that you live around Atlanta. Let's just say that if the Tesla tried to drive around the beltway at 50 MPH, I don't imagine that you'd be making very many friends. In that situation, the only thing the car could do is go on an understanding of "keep up with the flow of traffic" and speed up regardless of the posted speed limit.

During my trip, I dealt with some construction, and it made me wonder how the car would deal with things like lane shifting. Lane shifts don't always involve repainted lines, but are typically done with cones or barriers. How would the car deal with that? I could see it prioritizing cones over lines, but then again, it interprets quite a few things as cones that are definitely not cones. I've seen yellow fire hydrants classified as cones.

Tesla's AP is still learning. It has the best inputs/db to learn from and growing. Think of this as a 'kid' now. Eventually, it'll grow beyond any human capability.

I'm a bit curious to know how exactly they train the AutoPilot algorithm. Typically, AIs are trained on datasets that involve simulations using the aforementioned data that result in a pass/fail state. For example, Google's DeepMind trains to play against humans in StarCraft II by playing against itself, and if I recall, the winner's actions are compiled into the "hive mind" (very Zerg-like!). Do they use a driving simulation with AutoPilot (feeding it the applicable camera and distance data) to help train it?

Really?

I don't wanna know where you source your info from, but shows how you know nothing about Tesla's AP program. Well, most folks don't have a clue either but at least they don't say weird shit with magic involved.

Just working in the ML/autonomous controls group at a top research lab. You and the other Tesla evangelical here can play the forum reader non-experts all you want, I don’t care, but you’ll eventually see it won’t work like you expect. Your previous comment proves you don’t have a clue.

Environmental challenges are probably the easiest to deal with, assuming you have the necessary sensors. The real problem is that humans are highly unpredictable and crazy on the roads, and I'm not even referring to the worst of the bunch. Aikouka called it the nuances of human driving to contend with all the weirdness you'll encounter, but this understates the difficulty of a solution IMO. Most experts contend we are still years away from Level 5.

At this point, the competitive advantage of the AP "DB" is questionable. If all that mattered was the quantity of your inputs, then Tesla would be a lot closer to FSD by now. To take my point further, I think if you gave the entire Tesla AP dataset to Uber, they would never solve FSD. Most of the major players in autonomous driving have plenty of miles driven by now, so the quantity of inputs isn't a gating factor.

But the fanboy who makes bold, unsubstantiated claims about Tesla FSD's future says "Talk is cheap" LOL.

Took the Y out to Atlanta Dragway to see what it could do. The night started fairly warm with the car showing 90F at the start of the night with it cooling to the mid 70s. The DA was pretty bad at 2868ft thought it has much less impact on an EV.

All runs were withing a few hundredths of each other but the car never did better than the first time. Not sure that sitting for an hour between runs helps the car or tires stay at the best temps. Anyways, not bad to have a CUV that can drive to the track on AP, dip into the 11's and then quietly drive home on AP. Probably the most uninvolved drag strip experience that I've had

What was your state of charge? I know when I've seen people testing them, they'll try to get it as close to fully charged as they can as performance will dip as the car loses charge.

Oh, and I don't know how much people care about this sort of stuff, but I don't know if you'd prefer to blur/block out your license plate.

It was around 85% when I got there and and dropped to 82% when I left. I stopped at the closet charger to the track, but it was only a 30A ChargePoint so I didn't get it full. At least it was a free charger.

I blurred out the plate just in case.

30A is like what? 22miles / hr?
LOL... i think you will burn more then that doing a few runs.

Yeah, it was remarkably slow even compared to the 48A home charger which can do closer to 44 miles/hour. As far as battery usage, I only dropped 3% between 6:30 and 11:30 in which I got 4 runs in. That's roughly 8.5 miles of range lost which isn't bad factoring in drain when sitting.

A large part of my work consists of writing a very different type of autopilot ... main differences being 1. It’s for aircraft and 2. It actually works Pretty irrelevant to the discussion though. Keep up with the real research (you know, IEEE and the like, not blogs and forums) and you’ll agree with me.

AP is easy for the sky... there are no fire trucks, or concrete lane dividers for your plane to kamikaze though which tesla's are prone to do so. (sarcasm)

Now, this explains it well. You have the right not to have a clue what Tesla AP does. Still terrible.

Perhaps you should buy one of their vehicles instead. You heavily vocalize your support for them, you're buying shares to make personal profit off their work, yet you don't own any of their products. It's a bit odd. It would be like an Apple zealot not owning any Apple products.

I'll buy Tesla vehicles eventually. I'm on the list for Cybertruck Tri-Motor and along with Tesla solar roof. I support Tesla by owning their stock. Yes, I'm profiting off their work. Which is only fair since I own part of the company. Owning Tesla shares gives me ownership in the company along with voting rights. That's how stocks work.

But I haven't bought S3XY cars even though I really want one. I know the smarter play is to own Tesla shares than Tesla vehicles right now and the future. I believe Tesla stock price will 5X or more from current level in the next 10 years.

Have you earned enough to buy your CT yet? I kick myself for selling the stock. I'd have enough to pay for my CT if I wasn't so greedy.

This single TSLA January 15, 2021 $300 call option is enough to pay for my Cybertruck.



I purchased this TSLA $300 call option for $3,951 back in Sept 2019. So about 9 months ago or so. Today, this same call option is worth ~$70,600. I could sell it tomorrow for that if I wanted to. This call option gives me the right to buy 100 shares of TSLA stock at $300 /shr anytime til Jan 15, 2021. So you can say I'm buying my Cybertruck for $3,951.

I've made enough money from Tesla stock to easily buy fully loaded Model S, X, 3, Y, Cybertruck, and Roadster in cash along with Solar Roof with plenty of money left over. And all this is because I choose to buy Tesla stock and options instead of buying Model S.
