In Thailand when parking on the side of the road we parallel park. But in shopping centers everyone reverses into 90 degree parking spaces. When they are all full (they get full awfully quickly) people just parallel park infront of those cars. It is common courtesy here to leave your car in neutral, the parking brake off, and the front wheels straight ahead, so that the person you have boxed in can get out and push your car out of the way. On busy days you can have two rows of cars parallel parked infront of your car and you, with the help of a security guard, will have to push twelve cars out of the way before you can drive away.
