Punishment that your don’t need to pay if your just respect the legal speed. We’re not talking about someone stealing food because they can’t afford to eat, we’re talking about someone driving a car and being unable to get their foot off the gas pedal for a bit. Your reaction to that is “People shouldn’t take their responsibility to respect the law, it’s the state that should spend money to make it so they don’t want to drive like morons!” while ignoring the fact that speed cameras are proven to be effective at keeping people under the sites limit and cost way less than just rebuilding roads. Add to that the fact that your solution means years or even decades of people driving too fast for safety while roads are getting rebuilt based on their speed limit and there’s nothing to enforce the speed limit in the meantime because “speed cameras aren’t the solution”.
If you’re unable to slow down just because the road is wide enough that you feel safe driving fast then you’ve got no business owning a car.
