It's pretty easy to do so much damage. Imagine turning left without looking and an oncoming truck tries to avoid a collision and drives into a store front. Property damages will be very high and the injured people inside the store will need medical attention, too.
I caused something similar and accepted the accident as my fault.
I back-exited a parking space and turned left immediately after, while the truck tried to avoid me by going in the incoming lane; if he just hit the breaks without swerving I would most like have been killed.
