Prior to getting my MX, I have only owned manual transmission pickups, and I still own one. With a manual trans, you always drive two-footed, but the left foot is 100% for the clutch. I never used the left foot for the brake, especially whenever backing a trailer. Right foot for accelerator and brake 100% of the time. One one occasion, my daughter was towing her horse trailer and pulled the trailer down the hill of my driveway and parked at the house. So the task was now to back the horse trailer UP the driveway to exit. I did it for her when she asked. Every time I would let off the gas to adjust as I was backing uphill, I would have to let off the gas with right foot and depress the clutch with left foot and depress the brake with right foot simultaneously to keep the truck and trailer from rolling forwards. But then taking off from that stop with a manual trans - that's the real challenge. Let right foot off brake, press accelerator kind of a lot while simultaneously letting out the clutch to start moving the rig without stalling and without unintentionally rolling forward - fun stuff. The Tesla eliminates that challenge by allowing the brake to lock for you whenever you stop to adjust. Seems to me as if that would make it easier than the task I had, not harder. MX has tremendous towing power, so you're never challenged to make the car and trailer move, regardless of how steep the hill is. From what you're describing, sounds like the challenge is applying the correct pressure to the accelerator while backing up the hill. My guess is this will get easier as you back up that hill several more times. Like everything in life, there's a trick to it. Once you learn the trick, you're golden.
