Andrew, I feel your pain. I'd managed to leave my parking lights on when I made a trip to Austin. This was my first few days with the new 848 and I was so proud of it. I hopped on turned the key. Dead. I spent the next few hours trying to figure out what the hell happened when I realized it was my parking lights.
Eventually I was able to find my friends and have them push me through the parking garage and eventually successfully popped the clutch (much more difficult than in a car, the back end is so light I'd let the clutch out and the rear tire would lock up and skid. My buddy had to push and hop on with me). Also, I was nearly out of gas so I had to take it to fuel up. It hadn't quite charged enough to start up so we had to push start it AGAIN in front of what felt like the entire world.
