While I was exiting CHS morning drop off from the proper lane, male Lexus driver approached from next lane in parking lot (not an exit lane), attempting to cut me off, coming centimeters from my vehicle in order to run me off the parking lot so that he could get himself in front of me just to be able to exit before me. I laid my horn and he just kept coming. I guess being in front of me was more important to him than the possibility of an accident.
