my remote start if set in for a manual car, will only let you start it if it knows the car is in netural. The way it does this is - after the turbo timer has shut the car down, if a door is opened, it will not work until the car is runnning again.. this just means that if someone opens your car and puts it in gear without u realising, then u wont start it in gear. However, mine is set for auto, so I can start whenever - i never leave my cars in gear.
