"The policy is probably the de facto assumption that driving is a right: the United States has been rebuilt around the need to drive everywhere and the entire system tends to implicitly assume that anything which would impede someone from driving is unconscionable unless you get to the point of a serious collision or fatality."

They take away driver licenses all the time in the US though. DUIs being the most notable, but even getting enough tickets can result in losing your license, or having it suspended. I know at least a dozen people who lost their license at some point.
