I really don't care what happens to idiots when they do idiotic things. The danger of someone darting out into traffic while playing human Pacman causes me more concern for the damage to the car and potential mental trauma to the driver than for the idiot who did the darting. You roll the dice and you take your chances.
Anoter good on the surface idea is airborne taxi service. I'm all for new ideas for getting into town having commuted into Los Angeles. This one stinks. Problem #1: there is no graceful way to pull over should mechanical difficulties arise. I don't worry too much for the driver (pilot?) and passengers, they chose the risk. Commuting is bad enough, commuting with the risk of someone crashing into you from above is a little too much. Get hit from above, and it won't be a fender bender. Problem #2: Are security officials going to be keen on the idea of privately operated aircraft flying into the heart of the city? This service would be shut down with the slightest hiccup of the security level. Lastly, and not really part of risk assesment, $90 each way. I understand that fares would be route dependant and are comparable to ground taxi fares, but at that price, I can see why more people don't take ground taxis.
