This is an embarrassing but true tale that demonstrates how quickly habits can form. I have owned my MS P100D for a bit over 100 days and love pretty much everything about it. While traveling on business, I rented "normal" car and appreciated just how special the TESLA really is. Its an entirely different experience- which led to an embarrassing mistake. I pulled into my office at 7:30 am, gathered my personal effects and went to in to work. When I returned to my vehicle with a colleague to go to lunch we realized that I had left the keys in the ignition with the engine running for 5 hours. I know I am going to get flamed by the forum for being so absent minded and it was certainly a stupid mistake, but I cant help but wonder if any other TESLA drivers have had similar muscle memory blunders. Anyone?
