Speeding fines are if anything a tax on stupidity. If you aren't capable of reading numbers on a sign, or if you choose to speed, of seeing a brightly painted camera, or noticing a police van parked up, you probably also are so unobservant a driver that you're doing a bunch of other stupid things in your rush to get from a to b 5 minutes faster.
Whether or not speeding itself is dangerous is pretty irrelevant really, people who get caught speeding are way more likely to be dangerous drivers, due to their lack of observation skills. They all seem to think they're great drivers, but I bet if you look at the statistics, they have way more accidents – if that wasn't the case, insurance companies wouldn't bother to up their premiums. It would be great if we could remove from the road all the types of people who get caught speeding – make the world a lot safer without all those poor drivers.
