As a former Insight owner (I had one for 7 years, plus two co-workers at our shop also had them for several years) and now a current owner an EV I've gotta say you seem a bit delusional. You're using what is by far one of the cheapest cars to operate of all time, that you bought after its full depreciation, and is a tiny (1800 lbs) 2 seater with mountains of rattly tradeoffs as a justification for EVs being less efficient than gas cars.
The Insight is a fantastic car, don't get me wrong. I loved mine. The engine is very reliable, and requires very little upkeep.
But it has a gas engine, therefore it will eventually need all of these parts that WILL eventually wear out, possibly all at 200k, 300k etc.. but they will die:
-Valve seals
-Bottom end bearings
-Valve adjustments (

-Piston rings (it will burn oil eventually, if it doesn't already. Mine did by 160k, but not a lot)
-Oil pump (maybe at 500k, but some day)
-Oil changes should be every 7500 miles and once a year minimum
-Engine air filter
-Spark plugs (I changed mine every 100k. If you take them out you'll see they look awful by then. Also they're expensive on these cars)
-Injectors (eventually!), injector seals, fuel pump (maybe 200-300k depending on luck), fuel filters
-Clutch master and slave cylinders (these are notorious to fail on Insights and S2000s around 150k miles)
-Timing chain
-Timing chain tensioner
-Water pump and all related plumbing
-Mass air sensor
-Catalytic converter (mine threw a P0420 check engine lighat round 150k and it was always triggering this light. I guarantee the stock cat was failing. Google it, super common on Insights.)
-O2 sensors at the same time
-Muffler, exhaust manifold (maybe t'll last 500k miles)
-Clutch disc, pressure plate, and flywheel (mine was heavily worn by 130k miles and shuddered badly by the time I sold it at 200k. If your IMA goes, the clutch takes WAY more abuse because the long gearing)
-12V Starter motor (if your IMA dies, you'll have to use this instead)
-PCV, EGR, EVAP, related vac and fuel lines...
I could go on, but to use your reliable car as evidence that it will never require maintenance is silly. Shit breaks on gas cars all the time, especially over miles and years. They generate much more heat and have way more moving parts than an EV. I have a parts catalog and a huge repair manual for the Insight. It wouldn't exist if they didn't break.
Cool, but not everyone can do that. Oil changes can be a burden for many people that live in apartments or houses that don't have tools. Also your engine is extremely small (1 liter, 3 cyl) compared to most people. I work at an auto shop and have all those tools, and oil changes still suck because I have to bring it here and spend an hour on the lift, buy oil filters, buy oil, empty our barrel sooner because of it and so-on. That hassle is multiplied as an engine gets bigger. Even if you don't do the work, you have to take the car somewhere and wait for it, get a rental car, follow-up and so-on.
My girlfriend has a Honda Fit. I do all her oil changes. It sucks that I have to take her car to work on those days and service it. I'd rather drive my EV.
Time will tell but look at the Teslas and first gen Lithium EVs. They're good so far. How's the NIMH battery going to be? Dead. I know because I have replaced 3 of these on Insights. And my co-workers original Rav4 EV was traded in when the NIMH battery died and the replacement was $15k.
The car is GUTLESS without the IMA. 0-60 feels like 20 seconds, and the 0-30 is borderline dangerous. Also it's going to put more wear and tear on all the ICE components and really mixed driving gets about 45 MPG like that. Not 70 except at freeway speeds. I had mine disabled for 2-months while I waited on a replacement for the NIMH battery back when they were less common and only one guy was making them. It cost me about $1300 to replace myself then. Try turning it off for a couple weeks and you'll see how bad the car is without it.
NIMH was chosen at the time your car was created because it was the best part. Now it's not. New hybrids use Lithium AFAIK.
Lithium Ion was new, not practical, and not cheap at the time your car was created. NIMH has much lower density, so putting those in an EV means the battery pack weighs 50%+ more. If NIMH was still the best choice I think Tesla and others would be using them. Maybe this will all change with new battery chemistry in the future.
Hybrid batteries also see WAY more charge/discharge cycles than EVs, and that's what kills both types of these batteries. If you drive an Insight around town for 2 hours you might go through a dozen charge cycles. An EV (especially a Tesla or Bolt) would use one charge cycle every 240 miles. Hybrid batteries should wear out faster than large EV batteries. They're being used way more frequently.
I don't believe you can get 60 MPG towing a 1000 lb trailer unless it's streamlined and you're driving like 30 MPH. Also you're doing something pretty dangerous to be towing a 1000 lb trailer in an 1800 lb aluminum car designed to carry only 380 pounds including the driver, passenger, and cargo. You've got range, that's for sure. That's the real advantage of an ICE, and luckily I have 4 cars in my household for 2 people so I have a lot of choices. I know not everyone's this lucky and that's why I'm arguing only the cost benefits of EVs, not the practicality here.
Ignoring all the maintenance of our gas cars, 87 octane is $2.67/gallon average here. My girlfriend's Fit averages 35 MPG mostly freeway driving. This works out to $0.076 per mile before the maintenance, oil changes, time spent at gas stations, etc. Until we were switched to solar/wind, I monitored our electricity usage with the Smart meter system several times a week and our EV was going 45 miles (our average daily use) on 10.56 kW at $0.11 - $0.12/kWH. This works out to $1.16 - $1.27, or about $0.026 to $0.028 per mile, considerably less than even my Insight cost to run gas at 60 MPG and 1/3 the cost of the Fit. Gas is cheaper there and electricity is more there - so that benefits the gas car. Maybe if you have an EV you can get a power plan with cheaper rates at night (we did).
I'm sure many people in California are buying EVs because they are more economical here. We did the math and the EV is much cheaper. We drive the EV everywhere we can, especially on weekends and around town errands, short out of town trips etc. It's also quieter, more comfy (since the Fit is a buzzy high revving car at freeway speeds), and a lot zippier. She only uses the Fit for commuting, when we need the luggage space, or for long drives which we make a couple times per year. This way we have to do minimal maintenance on it and gas stops. Time = Money. Speaking of which, this is the biggest post I've ever made!
IMO the only gamble is the lithium drive battery. If it fails or needs repair, all this may be moot. If it doesn't in the time you own it, the EV is way cheaper from what I've seen, and saves a lot of time, especially if you get a used one. If it's cheapish, you might still come out ahead.
