I hear ya Dragline.
My only argument would be, based on what you just said, that if speed is an issue, why not set the speed limit at a point where car crashes wouldn't be deadly, if that is the main goal of speed limits? Cuz at 65 mph, youre just as dead-as-fuck as someone going 95 if you hit an oak tree, or another car coming towards you the opposite way. 65 or 95 wont matter much. Sure, you can argue that some people wont have time to react when pulling out into traffic when theres a guy going 100 mph down the road youre trying to get on. You can also argue that an 80 yr old lady pulling out of the church parking lot will have that same delay in reaction time with a guy on the road only going 50.
I guess what im trying to say is that, for me it all comes down to this lowest common denominator shit making the rules. Maybe I just dont give a fuck about slow people who cant deal. Slow reaction time? Stay off the god damn roads then.
Pretty harsh I know.
PS - If I was king of this country, there would be no speed limits, but if you messed someone up, or killed someone due to the speed you were driving, you get thrown on "the island" with the murderers. I think people might think a little harder about what speed they feel they can drive safe at.
