Let me weigh in on this. Some years ago I was driving from Houston to Lake Charles, Louisiana for a week long job at one of the many industrial facilities. As I passed through Beaumont, TX, the trafficon I-10 slowed and came to a stop in front of me. I slowed the rental car (a Camaro) and stopped with a little more than a car length of space between me and a Toyota in front of me. I looked up in the rearview mirror and saw this white pickup truck bearing down upon me.
He never hit the brakes and only at the last minute jerked the wheel to the left to try to avoid the collision. The rear glass went from clear, to white to black (the force of the impact). I'll never forget that sound. He hit the left rear of the car, drove my rental car forward towards the car in front of me. I saw his pickup truck pass over my left shoulder as he drove us forward, slam into the concrete "Jersey barricade," bounce off and hit the car in front of me that I was sliding towards, drove that car into the car in front of him. When he bounced off that car, he slid down the barricade wall until he came to a stop. Somehow, I got myself together, pushed the door open, checked on the drivers of the two cars in front of me, and then walked up to the pick up truck.
The right rear wheel was off the ground and the engine was still running at high speed. This guy and his girlfriend were slammed over to the left side of the truck and sort of pinned between the door and the steering wheel. I opened the passenger door, reached in and turned off the engine.
We were all lucky we weren't seriously hurt, but the two of them were having a bit of touchy feely time while barrelling down I-10. I didn't realize how bad I would feel just a couple of days later after the impact. The car was a total loss as it folded and twisted the frame of that Camaro. The impact snapped the seat back and I was driven forward so hard that my Ray Ban sport shooter glasses with the sports guard were driven into my left eye socket, cutting me.
As a result of that experience, I take a rather dim view of that sort of activity on the highway.
