The article claims that in Europe it has a 3 star crash rating, while other passenger cars are 4 or 5 stars.
The article talks about the "bigger car and truck" traffic composition in the USA. As discussed earlier in other threads, that's a risk alot of GasSavers choose to take.
I wouldn't compare the Smart to all other cars on the road. I would compare it to Metro/Swift's, CRX's and Yaris'.
In alot of ways I think of the Smart as an "enclosed motorcycle". Given the choice between a motorcycle and a Smart, I'll take the Smart. What would happen to a motorcycle driver in that video if they hit that low wall at 70 MPH? Can you spell meat rocket?
