The wildest concept cars of the year

I have been a long time skeptic of putting legs (instead of wheels) on Robots. Hyundai seems to take their concept seriously as they recently paid about $1.1 billion to acquire Youtube content creator Boston dynamics. The problem I see with it is they have many small moving parts on the leg structure that must carry the full vehicle weight. Add a lot of dirt/grime and they are going to be pretty high maintenance when most terrain it's intended to traverse can already be done so by rock crawlers with 4 large diameter wheels that can be built and worked on by teenagers instead of billion dollar robotics companies. If you were to put it through the stress of taking it off of a ramp for instance the legs would likely be badly mangled and broken. That means if it slips and falls there is a low survival rate for parts that are expensive and difficult to spare in locations where maintenance will be challenging. It's a design that will work OK if you have a team of support people and a maintenance trailer to support 15 minutes of operation at a time for some cool Youtube footage and fails spectacularly otherwise.
