Cyclists never do everything right, though. Contested stop signs are a prime example. For every cyclist who stops properly, 99 blaze through with attitude. They are lawless, and cause safety issues for drivers who have to deal with it.

You’ll also see them run red lights, cut off pedestrians, bike right into oncoming traffic (in the same lane, no less), cut across three lanes of without blinking. All in the name of laziness, not safety.

While I think cycling is great - environmentally, for health, apparently for mental health - bikes and cars don't mix unless they are going approx. the same speed in 1-2 lanes.

Driving a car, bicycles are hard to see - I wouldn't be surprised if visibility in cars is specified to be sufficient to see other cars. Bicycles appear out of nowhere and disappear. Also, cyclists - no better or worse than their automobile counterparts - don't always drive well, and they do things that cars don't such as weaving through small spaces between cars; running lights as if they are pedestrians, but on the road; appearing from sidewalks and other places - really anyplace. I don't object to creative driving - as I said, (city) drivers aren't much different in their way - but it makes bikes unpredictable and hard to see. Then there's the speed difference - bikes much slower than traffic are as dangerous as cars driving that speed (again, except I can see the cars). As long as there's one lane - and if cyclists 'own the lane' and don't let cars squeeze by - it's safe: you can see the bike; multiple lanes and the bike ends up in blind spots, weaving back and forth itself, etc.

I read that in (Belgium? The Netherlands?) the law is that if there is a small (10 km/h?) difference in speed between cars and bikes, they cannot share the road.
