A Texas resident and investigating police have not been able to figure out why a woman got out of her car last Thursday morning purely to key a Mustang parked in a driveway.

Corpus Christi Police have released surveillance video that shows a woman pull her white car into the front of a stranger's driveway, then scratch the boot, side and bonnet of the black sports car parked outside at 7.30am in the morning.

Clad in short shorts and white socks, the woman then marches back to her own car and drives away.

Police said the woman had also banged on the front door of the house and yelled, but surveillance footage of that has not been released.
