How about battery goes dead, you have to break your window? I?ve been researching McLarens since they?re a relative bargain. I?ve been looking mostly at the 650S, but apparently on the MP4-12C, when the battery dies, the last thing it does is lower the window a hair so you can open the dihedryl doors with a special key to get in to charge things. If that malfunctions, you have to break the window to open the door. Check out this video. Skip to 3:56 if you?re short on time:
