Interesting. On the surface this looks like a complex question with many layers of nuance and spheres of interest. Underneath there's one inconvenient question being avoided that bothers me. It is a slippery slope into a vile dystopia of mutually suspicious snitches. A society of people all filming each other, looking for minor transgressions is no kind of society at all. Just wait until the face recognition corpus is fair game and apps start popping up to ID strangers with shifty eyes and too swarthy skin. On the other hand, millions are injured on the roads, many drivers are idiots, and cars are so 20th century anyway. I can see how hostility foments on both sides. What is really going on here? I think we are killing the social contract by a thousand cuts. Isn't the cause that the police and local officials responsible for managing traffic don't do their job - usually because they are understaffed, underfunded and demotivated? This set s up a downward spiral. We are abandoning an expectation that our institutions of justice can and will do their job, because "there's an app for that!", and so a vigilante society needs to step up in their place. Apps like this tacitly condone disestablishment of police and law courts (of course they claim to merely 'complement' them), and by osmosis open the door for Big Tech to usurp their place (Cue app-store "police approved" calibrated apps that cut out the cops and just issue the ticket). Also, what countermeasures will soon be available to drivers in this technological arms race? Giving every citizen the power to be a cop has the hidden effect of giving everyone an equal and opposite motive to be a criminal. Much as I'd love to help prosecute the assholes who speed around my neighborhood I don't see this ending well in the long run.
