The Germans have (well, now it's had) no speed limits on their major highways....didn't have that many problems did they? Nope.
It's not speed thats the problem (going 100 or 140, you get hit your just as dead), it's the quality of drivers on the road. There are ALOT of VERY bad drivers on the road. I can't get over how incredibly bad people are at driving. No signalling, not paying attention, not pulling over for emergency vehicles (my major pet peeve).
I think people need to stop getting their knickers in a knot over speed and look at the real problem, the quality of drivers on the road. The majority of accidents I've almost been in were not a result of speed, but rather some blonde bimbo yacking on her cell going down Hwy 400 or some soccer mom driving her Suck Utility Vehicle in the middle of a two lane road (yes, in the middle), or some retard with a civic equipped with performance tires trying to drive in the winter.
Yeah, it's a touchy subject for me too. (I get 6 demerit points for a one time frig up while constantly bad drivers get to fiddle-frig their way around town giving me near constant heart attacks and they get bupkiss, and don't get me started on drunk drivers who get to stay on the road).
