It certainly has that effect, but I can assure you the intention of getting one was because of the standard of driving these days.
Plus:
1) my sister had a minor prang in NZ years ago and the driver just got out, blamed her and after the usual exchanges of blame, and some pretty obvious facts about the relative importance of each road at the junction, he said "you can't prove anything" and took off.
2) a boss had a similar incident but the driver took off without stopping. The boss was too cute for that one, so he reported it to the police and made sure his story was in place, in case the idiot reported it and the boss was on the back foot immediately. The other driver reported it an hour later and as a result got a letter from the boss's solicitor. End of. Except the cost of repair. Our company paid.

But with a video they would have got compensation via their insurance companies.

My point about driverless cars could be more serious. What if those braving the situation mistook a driverless car and it turned out the owner was drivng. And the driver didn't respond quite as quickly. Until all cars are driverless the potential for such errors of judgement is there.

I have my dashcam - what are you doing about it?
