What!? I'm not following your logic. If there is a warrant for your arrest, and law enforcement is tracking your phone, law enforcement can simply come pick you up in a squad car.
Do you actually think there are sufficient LEOs to run around chasing phones for every petty outstanding warrant? Why bother even trying when they can just be delivered by a robot.
Cities are ringed with rich suburbs with overstaffed police departments full of bored cops. I can see them being very interested in a product that scrapes cell subscriber and location data to ID people with outstanding warrants.
I fully agree with you that there's aren't sufficient resources to track down every deadbeat that failed to show up in court, or accumulated too many parking tickets or whatever. However, things that make it easier and cheaper to find people do not bode well for free society. Think about the kind of sigint that went into catching Bin Laden. Now imagine a world where 99% of that is automated and the police feel it's reasonable to use it to catch petty thieves.
I'm very likely to be the old dude driving a beat up classic driver's car with a home-grown performance-oriented EV conversion under the skirt.
As if there's zero risk associated in getting into someone else's car...
Not to mention any vehicle I willfully own will never barrage me with advertisements or surveil my movements.
Uber is burning billions of dollars in an attempt to corner the market. When/If they succeed, do you really think they won't put the screws to the customers living in circumstances where car ownership has likely become all but impossible?
The prices will shoot up, the monetization of the personal data will increase, the in-vehicle advertising will increase, the whole experience will become worse than what the end-game of yellow cabs looked like.
I fully expect the self-driving Ubers of the future to partner with the police in arresting people. You get in the car you ordered, it knows your identity, it reports all rides to the police system, if a boolean comes back true, the doors lock and it drives you to the jail entrance for processing. It's just another revenue stream.
