I agree and want to add that bad traffic laws can even cause more injury and death. There's research on speed limits that shows that they don't influence actual speeds all that much, people generally drive at what they think is a reasonable speed[0] regardless. But some people do follow them very strictly. So on roads with speed limits that are far too low you get people driving together at very different speeds, which results in more accidents. [0] I can't find the source right now but IIRC in one of the experiments they increased the speed limit by 5 mph on a highway, but the speeds driven only increased by 1 mph.
