Except if you observe a junction for a short while you'll see that in general people drive through even if there is no chance it would cause an accident.

The loophole for a cyclist is that they could swing their leg off the bike and magically become a pedestrian, cross the stop line, get back on, and legally ride away across the junction regardless of lights. Given that swinging your leg off the bike makes no reasonable difference to anything, why get annoyed if they don't bother with that part?
Isn't it just like claiming a general exemption on all amber lights because doing anything might cause an accident?
