Yeah keypress detection wasn't working, I rejiggered it. If this works OK I can modify it to make it work more like a conventional RC car. As-is, it continuously follows the last command until you press something else:

Thanks!!!

That error seems to be caused by the running the script from within IDLE, Make sure you're running straight from the terminal with "python gameboy.py"

I assume you also get the GPIO.setup warnings with your own working test scripts?
Found the cause of the GPIO.setup warnings and a way to take care of them:
Weird, the other scripts I was using that I generated were not giving me any warnings.
If it wasn't clear, it crashed after giving me warnings.
Yeah don't worry about the warnings for now, just run the script from the terminal and see if it works.
