Discription of Events: While driving on the south on Hwy 65 from Jeffersonville to Louisville, the vehicle approached from behind at a high rate of speed, straddling the lane divider. I noticed and swerved and honked. He then swerved like he was distracted and just noticed me… I sped up to 95mph to get the license plate and contemplated call 911. My exit to take the non-tolled bridge was ahead so I started moving over to the left side of the hwy. I could still see the car sped away in the outer right lane. Then he swerved to get into the exit to head to downtown, the same direction I was headed. I actually caught up to the car again due to heavy downtown traffic. We stayed in the same direction and stop light timing for about three lights. Then he sped up running through several red lights… out of my sight…
