We were driving on I-15 towards SLC, and merged in front of a truck to get over. He sped up, got around us and slammed on his breaks. Then he switched lanes with us and got side by side with us, so he could look at us. Then he proceeded to merge at us Into The lane we were in to drive us into the concrete barrier. We slammed on our brakes, then he sped off at about 110 down the freeway.

It was my first time encountering something like that, I truly believe that driver wanted to murder us. We called the cops and got off the freeway. People can be psycho.
