Yep, it happened. I never thought I would be that dumb to do such a thing (maybe the other Volt driver but no, not ME) but I did. This morning I pulled into our local Harris Teeter parking lot where there is a stop for the Express Bus down to Tysons Corner, VA and rushed to get out of the car because the bus was pulling up. I remember locking the door but thinking I forgot something else, such a weird feeling, but I got on the bus and forgot about it. Coming back in the afternoon, about 8 hours later, I noticed that my lights were still on. The first thought I had was that I sat on the key and accidentally started the car but I dismissed that as nearly impossible the way the key fob is designed. I walked up and lo and behold, the car was still on! Stupid me! So for all of you interested, I left the car this morning with 29 miles of range, it was about 35 degrees, and I left the radio and lights on. When I got back in the car, 17 miles of range was left! I guess not too bad for being on ALL DAY! Hopefully I didn't screw anything else up by doing that, but it drove fine afterwards!
