We don't need police-connected camera networks running machine learning in any US city.
Yes, we do. Every single car should be tracked. 40,000 people are killed every year due to car drivers, we should start taking this seriously.
There are better ways to increase driver and road safety than setting up an ever-present surveillance network in every city. I'm surprised by how many HN users argue against surveillance (for example some fuzzy ad tracking) and yet are fine with having recordings of every physical movement.
