Cellphones should turn off your WiFi and Bluetooth while you're in a moving vehicle.

Location tracking software is automatically turned on with most smartphones, which allows the cellphone to do a lot of task managing duties. Why not have the cellphone scan for Wi-Fi, and Bluetooth, and if there is neither when you are on the move then automatically have these features turn off. This would allow the owner of the phone to easily save his battery life by shutting down these features temporarily.
