>But then there are the trouble-makers and weirdos. Do you really want to be stuck on a bus or train, straining under shopping bags or holiday luggage, with some unpredictable idiot eyeing you?
I feel this is just as true as with driving a car or walking a street. My friend was hit by a drunkard running red lights (hey received no permanent injury, but did fly in quite an arc). I'm constantly weary of people not using turn signals and not looking to their sides, multiple times I've almost gotten hit. Lots of situations where one driver will stop in front of a zebra crossing, and someone on another lane speeds through like a guillotine. Tons of users signal they're turning in an intersection, then take that signal off and drive straight, leading you to almost T-bone them. Road-ragers like to drive in front of you and hit the brakes, people try to take over constantly when you try to keep a safe distance to the car in front of you.
In general I feel non-professional drivers are unsuited for cars.
