There are no specific requirements on avionics training. As long as you have been endorsed for a specific class and type of aircraft, you can fly one, even if the aircraft used for checkout had a different type of autopilot (or none at all).
Things obviously converge with more complex aircrafts, as it would be quite difficult to find, let's say, two Airbus A320 with drastically different stacks, but some of them, like Cessna 172 Skyhawk, have been in production since 1956, with aircraft technology making quite a progress in those 60 years.
If all your training has been done on a 1956 Cessna 172, is it wise to operate a 2016 model without sufficient training? No. Legal? Yes.
> Tesla does NOT put any requirement for more rigorous and stringent training for its drivers
Beyond saying "Don't take tour hands off the wheel and be prepared to take over any moment" what kind of training would you envision them offering outside of [insert state name] Driver's Handbook? Most states already offer free defensive driving courses as well.
