Since it seems to have rear wheel steering, if each wheel can turn independently and enough, then the car could be rotated in place.

- CoffeeOnWrite 4y agoThe article title says 80 degrees. My layman understanding is rotating in place means 90 degrees. Correct me if I'm wrong.
- Gravityloss 4y agoThink about a circle that has the center in the center of the car, and all wheels on the perimeter. Then each wheel has to turn along the tangent of the circle. That is the circle each wheel will go along when the vehicle is spinning in place. So it's less than 90 degrees. For example the left front wheel turns right, a bit less than 90 degrees.
- fauria 4y agoThat stationary spin is exactly what Rivian does, they call it "tank turn": https://www.youtube.com/watch?v=7BkxjHkOvYY https://www.youtube.com/watch?v=7BkxjHkOvYY
- mulmen 4y agoCan the system "tank turn" around an arbitrary point instead of the center of the vehicle? I can imagine some situations where a tank turn might be useful but a common scenario is parallel parking where I would prefer to pivot around the rear bumper.
- Gravityloss 4y agoNo, that's based on sideways slippage. How a tank or a Bobcat construction vehicle turns.
