Discription of Events: Turned off Washington onto Warrenville Road.at the dead end. I am a silver Lexus w50s plate z818417 comes flying by well over posted speed in the left lane. Like I was sitting still. Bust guess would be over 70. Immediately changes to the right lane in front of me to close. I just tapped the horn saying. Saying that was too close. No one immediately behind me. Keeps speeding to the second light where we are both turning right. He slammed on his brakes. Would not go back up to speed. Tapping the horn again. Would not go. Now that enough room and safe to go around. I try to. As soon as it was clear he guns it so he up my on me. At the next light by the Mobile gas station I did increase the distance do to this person playing games. Now taking photos of me. Turned and he followed me until north avenue and county farm. When he was stuck behind someone. He would cut off at least 5 other drivers 5 times. By north avenue when I was at least a 2/4 mile away he speed to catch up with me. Where I was turning right onto Saint Charles Road. Just not safe for others to be on the road and drive like this. When I was turning. It really felt like his road rage was to use his car to force me out of the way. Why following from Naperville not cool. Note car was from a Naperville dealership
