They didn't ambush the car - they were clearly blocking the road. Now, they did move around to make sure the car couldn't pass by them - but protestors and paparazzi do the exact same thing.
And the "decent" Israeli kept right on going after he hit the kid - that's a hit and run isn't it?
(Again, I agree with you, I'd have hit the gas too, but I'm simply putting this in context of what already occurs even in America. They do it for different reasons than our asshats, but they are all basically doing the same thing)
