I had an RC car as a kid that didn’t have steering. When it reversed, it turned left. That was the only directional control you had. I don’t know if it only had one motor, but I imagine it did.

Backup to turn one way was how they worked when I was a kid, but the also used a long cord instead of RF.

Plenty of old RC cars were wired.

Except “RC” literally stands for “remote controlled”.

What you had were uncontrolled toy cars.
