As a keen road cyclist in the UK I actually have bought an off-road bike because I simply don't trust US drivers.
In fact, the standard of driving here is frankly appalling. Tailgating and speeding is rampant. Lane surfing is rife. Couple that with just generally less safety street furniture at intersections and the laughably easy driving tests it's frightening really.
People say self driving cars are a danger, frequently the media report every Autopilot crash but what about the hundreds every day caused by some idiot texting? IMHO the sooner we take the distracted meatbag out of the driving equation, the better. I'm a car guy who just did a 2000 mile roadtrip to the Tail of the Dragon but this has to stop.
More enforcement and stricter penalties. Social stigma might be more powerful than this though.
