Here's an idea if some crafty person wants to set a world record and grab headlines for Tesla. Once autopilot lane keeping comes out someone needs to coordinate with a test track / closed circuit to attempt a world record for EV range. Set the cruise control at the optimum speed of 25-30mph turn on lane keeping and let sit back for 15 hours or so as the car does laps automatically. Here's a half baked plan for somebody in southern California to run with. The Mojave, CA supercharger is located about 5 miles from the Hyundai-Kia test track. Charge to 100% at the Mojave supercharger and then drive to the test track (pre-coordinated). They have a 240V outlet there so you can regain the 5 miles you lost getting to the track. Reset your trip counter/GPS logger and ease onto the track. Turn on autopilot at the optimum speed. The track has perfect lane markings so it should work great. I'm thinking that you might be able to get over 400 miles in a situation like this. You may need to plan it for cooler weather so that climate control is not needed. Anybody interested in trying to do this? Coordination with Hyundai/KIA is the hard part. They have opened the track before for a cycling event that I attended. BTW, I live near this track so I'd be willing to help support this effort however I can.
