I see myrkul is against speeding tickets. Because, if nobody gets hurt, no harm done, right? I should have the right to go as fast as I want, so long as nobody gets hurt, right?
Do I have the right to load a single bullet into a revolver, spin the chamber, aim at your head, and pull the trigger?
If the gun doesn't go off, no harm done. But if it does, then it's too late. Punishing me now won't bring you back to life. Therefore, there should be some deterrent against performing the aforementioned Russian Roulette scenario. Perhaps it's even morally wrong to endanger someone's life?
Simply put; In many cases you can own things that can endanger others (cars, guns (for now), swords, etc), but that does not give you the right to use them in a way that endangers others. In my state, the laws clearly allow anyone to counter a real threat against someone's life, including a 3rd party, with deadly force to stop it. None of that waiting for the bad guy to shoot you first, crap.
Back to speeding... Near and dear to me, because 1) I instruct types of high performance driving and have seen how badly people can f-up when faced with handling a car beyond its limits, and 2) I live where Janet Napolitano's legacy includes shoehorning 78 speed cameras into the state budget as revenue generating tools. Thank goodness the latter was repealed, but speeding enforcement was a hot topic for a few years, here.
Speed limits include a lot of factors. The one that is usually absent from forum discussions are how drivers react to situations that they need to stop, slow, or change direction suddenly. The US, like many countries, does not require drivers to prove they can handle cars with any slip angle on the tires. In almost every situation I've seen a driver on the road start to slide tires, they wind up losing control. I lost track of how many cars I've seen stuffed into highway guardrails because the driver grabbed the brakes as soon as the tires started to slide. Speed limits are kept artificially low to avoid putting drivers in situations where they need to control a car at/beyond the limit. I admire countries like Finland where getting a license requires driving your car beyond the limits on slippery surfaces while maintaining control. (Probably why so many top race car drivers come from Finland.) I'd say that any complaints about low speed limits should be directed towards either the average drivers, or the lack of training required for them to get a license.
