Would you rather be lawful, or improve everyone's chances of surviving the trip?

There are all kinds of things that the law says to do that isn't optimal. Sometimes the right thing to do isn't ideological, but realistic and practical. I agree everyone should collectively slow down, not because its lawful but because it is safer. But until they do, I will always pick the safer option over what is lawful. Lawfulness is not a barometer of ethics, its a tool of power.

Or we could build roads that accomodate the speed. However, the police and cities would just a major source of income by doing so. So, the alternative is to go with the flow of traffic, and be safer for it.

Cool if you want to pretend you're better than everyone, but the study above quite literally proves you're in the wrong, and a danger to others.
