Life is dangerous, and I'll just make my choices based on what works. I do like that our new 'Rolla has tons of safety gear, but I also ride motorcycles, climb mountains and other risky things. If I really wanted a Smart (and I would if it was a 3L/100km car) then I'd just figure that some compromises are required for such economy.
Hopefully as the Hummer population goes to the scrap heap, cars like the Smart won't be so vulnerable. We need to decrease the number of 3000kg behemoths on the road. It would be safer for EVERYONE.
