My gf has driven my golf once through necesity (long story). luckily she didnt hit anything but I was cringing every second watching her in the rear view mirror . never againĀ 
Similar thing here, let my gf drive my car , first time in the uk (she is from Iceland were they drive on the wrong fucn side)
she nearly hit every car parked on the left as soon as she set off,so I screamed ..'park the car NOW!' ,and she did! right into the curb, ruining my front bbs rm Lip
so she managed to ruin a wheel after only 500 meters, never Been so scared in my life!
