What happens when pebbles etc get into the mechanism? Think of the inferior model T tractor conversions with planetary gears on their wheels picking up rocks..
They only cost a katrillion dollars. And you can't find a shop that knows how to fix/replace them nor will warranty the work. That's a hard pass from me.
These would probably only be good for manufacturers/car dealerships/ect. places that have the cars sardined in and never drive them for real.
Probably super expensive tires. Most vehicles aren't fitted for them. Most people that need to parallel park know how to. Nice innovation, but not needed.
Has nobody seen driving fail videos on YouTube? People have enough problems trying to drive straight, now we're going add sideways. Can't wait to see those videos.
