OK, so the engine shuts off at idle. The LR guy in the video says that the engine will restart if it senses battery drain "like if you have the AC on"...
but without the engine running the AC will just blow hot air on you... so how would this work in traffic where you need to pump on the AC (hot day in a traffic jam), but the engine will be stopped???
Sorry, wrong link... scroll down and you'll find the Land Rover link.
