Until police came.
Bad smash at front of our house. One car bonnet smashed to pieces, both windscreen bullseye, side windows wrecked, engine smoking and fuel spilling out, glass on road.
Car one hit at back, not as bad. I checked all ok, offered use of phone.
Car one exchanged details and drove home. Car two the badly damaged one left car and walked home.
I thought you had to wait for police.
