Busting the myth of the “scofflaw cyclist” Danish Road Directorate studies reveal that while 66% of motorists routinely break road traffic laws only 5% of cyclists do so. Law breaking by cyclists is higher where there is no cycle-specific infrastructure.
Cyclists go through red lights when it makes sense. Who wants to wait for dumb traffic signals when the road is empty and the infrastructure been built to protect pedestrians from cars (and cars from cars).
If a cyclist goes through a red light, the cyclist is dead*. If a car goes through a red light, the cyclist dead.
*yes, technically it could be worse for others too
