The Smart may have a stubby hood, but there isn’t much under it but air. It’s safety in a frontal crash is OK. From the rear, not so great, because the engine is right behind you. It sits pretty low so probably pushes under the passenger cell, but I like my legs and feet and want to keep them. And in side crashes, these are not going to be good. Not much structure or space bwtween you and what’s hitting you.
But my real problem is that the gas mileage is ho-hum and the performance terrible. You could probably get equivalent mileage and performance from an Acord if you gave it a smaller engine. The Smart should be getting 50mpg routinely. With acceptable performance.
I see a lot of them here in San Francisco, but they do make some sense for people who have to park on the street. Every block has a couple of spaces between driveways that are too small for normal cars, but a Smart fits just fine. That saves having to circle the block and lets you park near homem Sometimes an IQ or Fiat 500 will also fit in those spots, but sometimes just a Smart. I suppose if all your driving is short distances on city streets the performance limitations wouldn’t be too bothersome, but I wouldn’t want a freeway commute in one.
