The best thing you can do is this when starting your car
1. Open the door
2. Sit in the seat and make yourself feel most comofrtable
3. Put on your seatbelt
4. Place the key in the ignition
5. Ensure it is out of gear
6. Start the engine
7. Drive away after selecting gear and checking your mirrors
If this simple process doesnt work you could always slump back into your living room setee, unbuckle your trousers, kick your legs over your head and smoke your own rod.
Hope this helps, best regards
