Smart Cars are very “safe” from a structural standpoint. I think they’re ugly and stupid, since they’re no more economical than a number of far more practical small four door sedans, but they are well engineered. What happens in real life, though, is that their light weight does cause them to basically bounce off of heavy impact. That’s what you’re seeing there. They also have a bit of a higher center of gravity compared to most small cars. To me they look vaguely like a phone booth on wheels, they’re as tall as they are long, and taller than they are wide.
As Trump might say, "Not smart."
