Here's the deal: the U.S. has the most stringent crash and safety standards, necessitating design compromises that add a lot of unnecessary weight. Unfortunately, all these safety doo-dads only mask and serve as a crutch for the real problem: American drivers are wreckless and inattentive. I see it everyday: drivers smoking, drinking, eating, texting, shaving, dialing, iPod'ing... it's really come to the point where Volvo is advertising new tech that beeps when a car is in a blindspot during a lane change and auto-brakes when sensing a potential collision. Really? Wouldn't an attentive driver make such things superfluous?
Once we become as a whole better, more serious drivers, we can all feel better driving smaller, lighter cars and not these behemoth SUVs strictly for the fact that we feel safer on the roads filled with other behemoth SUVs.
Oh, and we really, really need to infuse life back into a transcontinental rail system, the same system that GM derailed (no pun intended) back in the 1920s and is paying back in Karma. This will take a lot of the big rigs off the road, easing congestion and a large dependancy on oil.
