Looks 90% good to me.

Not sure on the specifics, but please double check that TeleopInstructions aren't being voided or null'd as the program runs, and double check that the only driver for PID Output is your thread.

If you can, test in person. If you can't, let's pair you up with someone and get it tested before we merge.
