I used to commute between Kuala Lumpur and Bandar Seri Begawan when the older kids went on to secondary school. Finish work on Friday, board 18:00 flight to KL. Sunday, catch 21.30 flight back to Bandar. Arriving at BSB one night I couldn't find my car keys. Oh No! Left in KL! I'll see if I can get into the car and hot wire it. Try car door and find it unlocked. Keys? There they are - still in the ignition!.
Bandar Seri Begawan airport car park is (or was at that time) probably the only one in the world where you can park your car in the airport car park with the keys in the ignition and find it still there two days later.
Oh yes, and it started first try. Good old Mazda 929.
