It's impossible to get hit by cars if there are no cars around you. Vehicles are not going to materialize out of nowhere and crash into you. They are going to be funneled into your path by the roads. If you look at the road and see zero traffic, then you cannot be hit by traffic. Even if you run a red light.

Obviously, if you can't see the road where the cars will come from, then you cannot know if there are any cars coming towards you in a potentially intersecting trajectory.
