Just a couple of thoughts here - why is it in a country as big and wide as the United States have lower speed limits than compact Europe? I mean, take a country like Germany or England, with the longest distance that's possible to travel limited to about 800 miles or so, and yet they still have 130 kph or even unlimited speed limits on the autobahns. Even in the UK, the speed limits on the congested motorway system is 70 mph, compared to 55 mph in some of the northeastern states here in the US.
Things like speed cameras are nothing more than a money-making machine, and laws should be passed to keep them from being used. Anybody wanna start a petition? And this talk about driving being a privilege, well, they need to provide some decent alternatives to driving before they systematically take away this "privilege" for millions of drivers.
How about we do the sensible thing and start taxing the hell out of gasoline, now, while it's dirt cheap, and then start layering new car taxes based on fuel efficiency - SUV's get majorly taxed (commercial work trucks would get a biz exemption as to not hurt farmers, etc), and hybrids would get a tax rebate. Use these funds to construct new rail lines and public transport options so that people have other ways of getting around without having to rely solely on cars. Make it expensive and troublesome to obtain a driver's license, like they do in Germany. And let's stop building new freeways that are designed for 75 mph travel while we're at it, too.
But I guess these things make too much sense, huh? They'd rather make Montanans drive 55 on a 75 mph Interstate and put speed cameras out in the middle of nowhere to pop unsuspecting drivers for doing 1 mph over the limit.

Nowhere to run, nowhere to hide...
...and the meek shall inherit the Earth!
