Great point. Out of curiosity, what happened in the accident that the driver was comfortable inviting you into his car? In many environments/scenarios that would seem risky, particularly after a traumatic event like a car accident.
He had almost crashed into me by suddenly changing into my lane on a snow-covered highway.
I braked to avoid the collision, he swerved back into his lane having seen me brake, but my car rotated from the too-agressive braking. I was able to prevent a spin, instead limiting it to some highway-speed unpleasant fishtailing, but the whole ordeal had brought my car awfully near his trailer which was now next to my car again due to his decelerating.
There was a lot of snow/slush accumulated between the lanes, and this kept pulling the right side of my car closer to his trailer, regardless of what I did, before the tires of his trailer struck the rear corner my car, violently forcing my car under the trailer, shattering the driver and passenger windows from the compression. At that point it was pure chaos from above and the steering wheel was ripped from my hands by a frontal impact with the landing gear.
Somehow after what seemed like an eternity my car broke free from captivity under the trailer and shot out the side and off the highway, through the air, before landing on an embankment and sledding down to a frozen water retention pond where it circled a few times before coming to a stop in complete silence.
I can't speak to what was going through the trucker's mind when I knocked on his passenger window and told him I was the luckiest person on the planet, and asked if I could wait in his cabin until the police arrived. My car was not even visible from the highway. He claimed to have no idea what happened, just that he saw my headlights disappear after he swerved. He had no idea my car had been under his trailer. Typing this story has been surprisingly emotional.
I'm a truck driver, and I was a little sickened reading it. Still am.
Back in driving school one of the other students was out on the road with an instructor and two other students in the back. A driver was texting, and ran into the back bumper of the trailer (the iron work below the back door), embedding the car by the engine under the bumper. The car was dragged from that point until the truck stopped.
The story the student and instructor told literally involved the phrase "... did you feel something?"
