I believe they are kei cars. I looked up the safety ratings on them when I heard about them, and the D.O.T. equivalent board that rated them gave them 5 stars. But it could be that was a kei car specific rating. It did show diagrams with front and side air bags, and all the electronic crash avoidance systems. It’s bigger and seems like it would be safer than a smart car. I honestly think the hold up is that if we had options like that in the US fewer bigger, more expensive, cars would be sold. Maybe not a lot fewer, but enough fewer that it is overall more profitable not to offer them.
