Turning on the spot
Electric cars ought to be able to turn on a dime by reversing the wheels on one side... | |
Assuming your electric car is of the type that is a motor driving
each wheel independently (on all 4 wheels, which I believe is a
common practise with electric cars), ... it should be possible to
turn an electric car on the spot the same way that tanks do -
wheels on one side go forward, wheels
on the other side go in
reverse. The facility could even be downloaded as an upgrade
to existing vehicle. Note to the commenters: I'm not talking
about 4-wheel steering or differential steering or mecanum
wheels or anything that requires a redesign of any part of the
vehicle - I'm only suggesting that they could run the two wheels
on one side in reverse, on vehicles that have motors on all 4
wheels.

If you had some kind of independent steering control of all 4 wheels you could just pull a lever to engage spinning mode and all four wheels would toe-in front and back. |
|

You would get 'scrubbing' on the tires as the back ones at least
wouldn't be able to turn. Probably no more than turning the
front wheels while stationary I guess. |

Insufficiently original. [-] |

Serious tire scrub action and damage to sidewalls
likely. |
