I know it sounds stupid, but for the moment I think a simple app that doesn't let you text and drive will do the trick. Google will likely do something first though because they have the technology already. But so does Uber which is owned by them so I would guess it would be easy to manipulate the code thus evening the roads out
And have a bunch of people on them that can't drive without knowing the faster route. On too much road for the lack of police to cover. Create an app (maybe partner with Google) and increase the code on their algorithm. Everyone will use an app to get to work faster. Also by putting more traffic cops on the road, people will get more tickets and have their licenses revoked.
