There's a lot of other problems with everyone else's attitude in this thread.

There's an awful lot of fundamental attribution error. "Everyone else gets into accidents because they're morons, I'm a safe driver so I can handle speeding".

One problem is that you're not likely to have an accident when you're driving at your best, you're likely to have an accident when you're driving at your worst. So its more likely when you're going through a messy breakup or divorce or stress at the job, haven't had enough sleep, etc. That shitty driver may very well be you on a bad day (and this may be one of the worst times of your life that you've had for a decade.

The next problem is that even if you're a good driver and you're not otherwise at fault the speed limits are there to limit the damage when other people fuck up and get into accidents with you. If someone turns left in front of you without right of way and causes a collision, both of you will do better if you're not traveling that fast.

Similarly those kinds of situations can be caused by speeding because the human optical system is very crappy at judging closing velocity and things like that. Your car doesn't have a bubble over it displaying its current speed like this was some kind of video game. And other road users are allowed to make assumptions that your rate of speed is reasonable for the road and conditions. The people who drive fast and road rage about getting cut off are often creating that problem themselves.

And then if you're excusing speed limits, what else are you excusing? Do you not come to complete stops at stop signs when you don't see anyone there? Do you always signal even when you don't think anyone is around to see it? Do you come to a stop before the pedestrian crosswalk? Do you tailgate? Do you have the mistaken and backwards belief that traffic goes faster when people tailgate? Do you feel that you need to tailgate in order to avoid being "cut off" and that this has any measurable effect on the time when you get to your destination?

If you think speeding doesn't matter you probably believe some or all of these which means that the bad driver who shouldn't speed so they don't cause accidents may really be you.

So yeah the point of speed limits isn't necessarily about your or your mad skillz and fancy traction control in your expensive car, its about limiting the kinetic energy if someone else makes a mistake around you.

Speed absolutely matters because all of us make mistakes, and mistakes shouldn't be a death penalty for anyone. If you think your $200k car gives you the right to drive 15 mph over the limit in residential neighborhoods, and some dumbass kid who runs out in the road deserves to die for it, then you might be a sociopath.

And really GIVEN how horribly irresponsible everyone attitudes in this thread are around speeding, that makes me quite okay that we're going down this path towards decentralized surveillance. You all don't even recognize that there's any kind of a problem with velocity and kinetic energy. I sort of don't care if your rights and privacy get invaded at this point because a lot of you in this thread are pretty awful.

If we can't reach an agreement to be responsible and think about the welfare of others, then bring on the decentralized nanny state where we're all tattling on each other I guess.
