Bicyclists should wait at red lights just like everyone else, for example. It doesn't mean "stop, look, then proceed if you don't see a car crossing". It means you wait until it turns green.
Why? You make an assertion without providing a reason. Starting at the same time as cars exposes bicyclists to the risk of both right hooks and left hooks. Fully stoppimg also means that the bike is longer on the crossroads. If the crossing road is obviously clear of traffic, it can be safer to run the light. At least thats what a study conducted in Paris concluded. As a result, bicyclists are now explicitly allowed to run red lights at a few marked crossings.
