1) You're not serious? If people weren't speeding cops could do other things. Now they have to watch over people who can't follow the rules. That cop would could have been put to better use than to catch speeders. Helping somebody's granny over a street or something.
2) That's his risk to take when he's on the race track. Not on a public road. The harm he has potential to do increases, and he has no right to take that decision for everybody else on the road.
3) More fuel burned, more pollution. WTF does cost have to do with anything? People nearby breathe in more pollution, that's harm. And if you agree with +90% of the climate scientists you also contribute to global warming, admittedly not by much though. Still harmful to the environment.
4) Nope, not harm. I agree with that. Didn't say it was though. Just that there are rules and you either follow them or accept the consequences.
1) If cops didn't
chase speeders, they could do something else.
2) Still not actually harming anyone. Should you be arrested because you
might throw a brick through a window?
3) You're defending a Speeding ticket (Charging him a fine) by saying that goes to defray costs caused by increased pollution. That cost is already factored into the price of the gasoline.
4) No harm, no foul. He didn't hurt anyone, so why are you defending the extortionists in blue?
