Due care is another name for “due regard.”
Due regard means the regard that is appropriate given the totality of the circumstances.
The concept is taught during police training.
Example: police officer can use lights and siren when responding to calls, exceed the speed limit and go through red lights. However, said officer cannot blindly run a red light at 100 mph. Officer needs to approach intersection and make sure there is a clear path before proceeding.
Same concept here. If you deliberately aim your car into the middle of the rioters and hit the gas, you are probably going to have a problem. If you turn toward an opening and do you best to avoid any rioters (but they happen to get caught by your car and run over) that will be different.
and the scenario where there is no opening...?
