I tell this to anyone who rages: You drive and meet a LOT of people on your way. You don't make a lot of mistakes, but you make a few at least every drive.
Now given that you meet a lot of people you are most likely seeing a ton of mistakes by people. But individually they are not really making many mistakes.
Sure some people are horrible, but not all. And often the horrible ones are behind you.
And also, no matter how "safe" you are, it only takes 1 mistake to kill a person. Example, yesterday I was driving, a guy went nuts behind me and almost killed a motorcyclist. I saw that and it distracted me long enough to almost not notice the car that short-stopped in front of me. Literally 2 more seconds and it would have been a wreck. And I consider myself a safe driver, but it only takes one moment of distraction.
Basically what you're doing is playing Russian roulette, and you keep "winning", well yeah, that happens, right up until it doesn't.
Drive like a Google car. Stop being an idiot. Get a smiley face score.
This app and the related one about insurance liability (posted here maybe a week or two ago) would unfairly rate me, because I go against the risk model and win consistently. I also agree that there are MANY "safe" drivers whose indecision and timid driving leads to bad situations; merging at 45mph, slowing way down for ramps, stoping at yield signs, driving under the speed of traffic, braking unnecessarily in traffic, etc. However, since in my situation, the insurance company gets to charge me a lot more, they're incentivized against modeling drivers like me as less risky than someone who is involved in more accidents than me but drives well within the limits and doesn't understand what happens when they approach or exceed them.
I wouldn't expect that to be a yes/no thing. Shouldn't it be based on compared to the average driver, as determined by the same system?
All I can see this accomplishing is adding yet one more gadget app for people to be distracted by.
