This video is the same as the previous except it has an additional segment. The car goes down the hall, turns around and comes all the way back to me!!

Ioannis, I agree a potentiometer driven by a servo controlling direct current into the wheel motor would give the PIC smooth speed control.
For this home project with only my personal resources that is a complication I hope to avoid.

I would like some help directing me to a way to make interrupt driven PWM pulses delivered 50 times per second. My impression is with PBP GOSUB does not include arguments. This is very restricting. Am I correct?
