Maybe it is my european upbringing, but this is not my problem, but the problem of said company. I don't see why they should be allowed to test on public streets.
Just the insurance savings alone could give up to $800 billion back to rate payers in the US.
Let me guess, cars are king that's why we should sacrifice our kids to their cold hard steel bodies. /s
No seriously. This saving money doesn't mean they should be allowed to cut corners. If you truly want self driving you should be behind not using public roads as experimental tracks (with all the fallout that could come from that).
In the meantime, in the here and now, these things are obviously hazardous and shouldn't be on the public roads. Even if they would lead to a better future, no company has the right to endanger unconsenting others now to accomplish it.
When? What's the social cost to affording these companies public spaces to test their products?
Tesla's approach specifically is just hubris/greed with the commons footing the bill.
