Nichrome and Tungsten are PTC resistors much more than Copper. Note this helps limit motor max current due to DCR of coil when starting or end-stop.

Is it Constantan, or similar name, that has a constant resistance with temperature. I used to have an ancient reel of the stuff, rescued from scrap, that was dead handy for making power resistors, including variable resistors, for battery chargers, power supplies, and transistor power amplifiers.Nichrome and Tungsten are PTC resistors much more than Copper.

There will be a potentiometer that provides feedback of the steering direction.

So these cars had servo feedback control?
