Hi,
First of all, I wanna thank you guys for making a great show every week!
I would really like to see you guys build a gokart with a dc motor. Maybe salvaged from an old power drill? I guess that wouldn't be too complicated and take too much time? I hope at least 
And if you have some spare time, you could maybe make the steering electronic with a stepper motor and a potentiometer for a steering wheel? And also! 
you could "teslafy" it by adding an autopilot, or at least make it brake automatically with some scanning motion sensors?
Once again, thanks for a great show!
