I talked to a taxi driver about 2-3 months ago why he, personally, was so against Uber. He kind of sputtered for a moment then said something like "people want to earn money so they go out and buy a car and join up with Uber. They are not professionals and they are dangerous."
Of course, that isn't the real reason that taxi drivers don't like Uber, unless they are all truly idiots.
So I wonder how the mafia...er, sorry, the taxi union (and other transportation unions, like the union that serves truck drivers) is going to take this? I can see these guys hunting driver-less cars and trucks and causing them to stop...or even worse, causing them to wreck and then blaming auto-driving cars and trucks as the problem.
It's one thing to want to test something like this in a place that would stress the system and find issues, quite another to actually deal with the population of the city...
