 Yeah, between the batteries being affected by the heat and the air conditioner. I've heard a lot of people complaining that their air conditioner is not working as well as it should. Well, you think about it a little bit. Say when you get out of work or walk across the parking lot and you feel that heat. I mean, even with the air on driving down the road and if you get stuck in traffic, give yourself a little bit of room from the other vehicle, at least 10 feet, mainly because of the fact you have their hot exhaust.
