Leave it to the French to try something different--a new prototype platform for electric cars from Citroen doesn't need to steer the wheels, because normal (cylindrical) wheels are replaced by spherical tires, made specially by Goodyear. https://www.tiretechnologyinternational.com/news/new-tires-news/goodyear-develops-bespoke-eagle-360-spherical-concept-tire-for-citroen.html
Goodyear introduced the Eagle 360 concept at the Geneva International Motor Show in 2016, with a second iteration, the Eagle 360 Urban concept, following in 2017. The latest iteration of the design features a high level of maneuverability (due to the tire’s spherical shape) and long-lasting attributes (thanks to a tread surface that is four times larger than a standard tire). The tire provides extended range due to a low-rolling-resistance rubber and consistent grip in all driving directions thanks to hexagonal siping.

Yeah, and I also remember the problems that those mice often had, when the ball wouldn't rotate because it picked up some dirt. And the mouse was operated on a relatively clean surface, not on a dirty road.
