Crazy Lady Driver in QV Carpark

Yesterday TY and I were going out from the QV carpark and saw this lady driver in a silver Honda go over humps really slow and then take corners really sharp and fast. And if you see the QV carpark, the narrow ramps are 2-way streets, so you really should go slow... But this lady would speed off after every ramp. The good thing was that we were following her - probably wouldn't want to be on the other side coming up towards her... Scary stuff!!
