The driver intentionally ran me off the side of the road where two lanes merge into one. The car was to the side but slightly behind me, so I sped up to make room for him behind me, and he continued to speed up and swerved very close to my car. I then tried to slow down to let him in front of me because he was unwilling to slow down, and he slowed down to match my speed. I ran out of road and drove halfway into a ditch on the side while the car sped off, and the car behind his car let me back onto the road.
