You are being absurdly paranoid over what is essentially a non-event. You could make the argument that driving your car 10 miles during an oil change was unnecessary and I would likely agree with you on that. It still wouldn't be worthy of the energy required to write this thread, but I would probably agree they were out of line.
I want to know why it happened. That makes me curious, not paranoid. I don't think there's a conspiracy at the dealership to purposely drop french fries under people's seats during oil changes. Also, I don't understand the point of a forum if not to relay life events and have discussions such as this.
As for setting off the hard braking alert - BFD. I used to make a game out of it in my cars, I averaged once per mile in the Viper. It just doesn't make enough difference to get worked up over.
I'm interested in a 30% discount that's permanently applied to my account, so I care a lot, actually. If you don't mind pissing away hundreds of dollars just to make a point, have at it.
When I had my Progressive SnapShot I believe the threshold for hard braking was 10mph/s. That's absolutely absurd and far too low a threshold even for normal cars and triggering it is no indication of risky driving.
Your opinion about the threshold contradicts data that describes the average driver. I've said a few times now that I've driven for 1,200 miles without tripping it and I don't drive like a grandma. Over 90% of drivers stay at or below the allowance according to my insurance agent, which makes the threshold sufficient to categorize average, low-risk drivers separately from high-risk drivers.
In short, worry less about the small stuff.
I'm not worried about this, but that's not the same as wanting to know the answer to a question, which is reasonable. If I was worried, I would have driven back to the dealership on Saturday. I understand what you're saying, but I don't think it applies to me in this particular situation. I noticed something off and I'd like to have a conversation about it because my preference is for things like that to not happen. Assuming they provide a valid explanation, I'll continue going to that dealership. If I was upset, I wouldn't even be entertaining that idea.
Another point people seem to be missing - you can be the best driver in the world, but if you have to drive in high-risk situations, such as rush hour with people constantly cutting you off, that doesn't invalidate the model
at all. If you're more likely to have an accident, that's the result regardless of if you were cut off or not. There's no valid argument to be made against this type of statistic because a single person can only offer anecdotal evidence, which is what all of us have done. Based on my limited experience, I've found the threshold to be perfectly reasonable; additionally, my agent provided data to corroborate my observations.
I sent an email to the SmartRide (the company who manufacturers and maintains the device used by Nationwide) to see if they'll provide additional details. I specifically asked for data about the braking allowance from their point of view. They may not respond, but it will be interesting if they do.
