I know electric cars don’t need multiple gears, but wouldn’t they benefit from them in anyway at high speed for example?

We can draw analogy from trains.
Diesel locomotives of trains are actually diesel-electric. Transmission adds so much weight to the system, that it’s impractical. The Diesel engine is actually just a generator and electric motors are mounted directly on the wheels/axels.

Much like we see in fans, you don’t need transmissions/gears to change torque/speed. Changing the input does the trick.
