The hobby car using HPWM seems to behave correctly.

I need to calibrate the wheel torques associated with the various PWM pulse sizes. The steering servo seems slow. I know it can work well because it did so with the radio receiver in charge.

My proto is too fragile to run the car on the floor. I have it up on a stand making the wheels free. It runs on its own 7.2V battery unattached to the USB port. I can make it think there are walls near by using an oak cutting board to fool the proximity detectors.

Once this thing makes sense I will post a video.
