I get this all the time. "Do you feel safe in that thing?" I am constantly asked.
I always answer the same way: "I didn't buy it to feel safe. It IS safe - just google Smart Safety if you doubt it. I bought it because in 12-24 months, with oil on its current path, I will be the largest car on the road and then you'll be asking that question to the guy on the motorbike".
I also tell them that 1600 lbs curb weight, I'm going to bounce off of most things I collide with since I have such little mass. My biggest concern is my internal organs staying connected with the sudden deceleration - not getting smashed. But speaking of smashed, google the video where those three car guys in the UK ran a Smart into a brick wall at 70 mph. Yea it took a good a spank but guess what? The cabin was still in tact.
Safety is going be a small issue when all the SUV's are benched because of $8/gallon gas.
Americans wake up! We are STEALING petrol from the world at our current $4/gallon. The price in Europe is close to (US) $10/gallon so we still have a long way to go to pay what everyone pays - and trust me, we'll get there sooner rather than later.
