Seriously? This is easily the worst argument against bicycles I see bought up again and again. Next time you're driving count how many people you see breaking the law be it bicycle, pedestrian or motor vehicle. Now count how many you see receiving fines/being talked to by the police.

But let's go ahead and agree with you and add number plates to bicycles - ignoring the huge costs incurred by the state - how exactly does that help enforce any laws? Bicycles are to small and light to trigger most red light cameras and to slow for speed cameras. So you're only left with visual enforcement by an officer of the law, which will have to physically stop the offender to issue any fines... which... o, hey... you don't need a number plate for that.

If I don't count minor speeding (<10 mph over), I see a much higher percentage of cyclists breaking the law than cars. I drive through a busy four way stop while commuting and nearly every bicyclist does not stop and about half don't even slow down. I don't think I've ever seen a car just completely blow right through the intersection.

Interesting that's likely a location thing. Also I'd question < 10mph over isn't speeding, assuming even a 60mph speed limit you're allowing drivers to travel at over 10% faster than posted.

Depending again on location, there's almost definitely laws on indicating turns which I'd say is probably the one I see ignored the most (to cut off the 'I see bicycles not indicating' line, most places have a 'when safe to do so' clause for bicycles).
