I don't understand how it could be at all controversial that different vehicles require different regulations. 18 wheelers are not allowed to go everywhere cars can go and cars should not be allowed to go everywhere cyclists and pedestrians can go. Cars are an order of magnitude heavier and faster than a bicycle and significantly restrict the visibility of their operator - they are far more dangerous and the law should reflect that.
