If cyclists want to ride on the roads that are predominantly used by cars they should have to follow the same traffic laws as cars so they are as predictable as cars. Pedestrians walking on the road have a strict set of rules to keep everyone safe. Alternatively, they should be barred from riding on roads and have their own rules which would make them equally predictable.

Northern Virginia has some of the worst drivers I've seen anywhere in the country but you can predict that they're going to run a red light up until 5 seconds after it's changed or that they're going to race past a line of stopped cars and try to cut into an exit at the last moment while texting.

Cyclists here are a completely different breed and are in no way predictable. I've seen them riding into on-coming traffic, ditch off a road onto a sidewalk to cross an intersection only to jump back onto the road after the intersection. I've seen more near misses with pedestrians in cross walks and cars making a right on red than I can possibly count.

Because they don't consistently follow any rules whatsoever they're dangerous and the majority of them have an holier than thou attitude because they're not ruining the environment. They're just ruining every driver and pedestrian's commute.
