A colleague of mine has one. They are easy to overlook and he sometimes has pretty bad looking crashes (from the outside) but the chassis themselfs are extremely sturdy and protecting. He slid down a road 25m at one point, crashing into a pole, but only got a bruise from it. Because, and that’s the main point: these things are not going down 50mph, they are at 18mph and the only dangerous parts are intersections where cars are slower anyways
