Nav scaling fixed the steering lock-in, extending training to 100,000 steps gave the CNN room to actually learn road geometry, and every metric in that closi00

The actor finally had somewhere to go. Which meant, for the first time, the car actually moved. It also meant a new set of problems, because "moving" and "driving well" turne00

I wanted a base to build on first, a shape for the whole thing before I touched a single line of Python. So the first question I h00
