Just saw a true scenario this is a straight stretch of HDB parking area. A lorry waited for a parking lot at the front of the entrance to wait for any "Out going" cars. A passenger walking towards his car was just getting out at that time, then zoom came in a sedan car going in all the way towards the "outgoing" lot. The lorry follow behind and went head in after the car left, completely ignoring the sedan.

Sedan driver argue with lorry driver.

Who is right and who should have this parking lot ?
