But that is the interesting thing: tickets and fines are intended to discourage bad behavior that is slightly antisocial. (as opposed to murdering people, which is highly antisocial). With the advent of autonomous cars, mission accomplished. If you ticket the manufacturer, you incentivize them into creating a better, safer, product.
There will still be plenty of tickets to write for a long time, as until we are at 100% adoption, people will still break trafic laws. Also, I 'm sure that hacking the robodriver software will be a popular thing for teenagers to do in the next decade or two. That should be worth a huge fine, if you did it with intent to speed, race, or run people over, since a speeding ticket is generally intended to be a "2nd degree reckless endangerment" charge. It would give you ample proof of intent.
