i was driving in the slow lane @ 65mph. the reported car was approaching at a very high speed and got so close that i braced for impact. they swerved and almost lost control. they tried to blend with other traffic, so i was able to catch and record the plate number. the flow of traffic forced me to move ahead of the hyundai. The driver again ran up on me at high speed. i have a fast car so i got ahead and off the indiantown exit.
