Levston said the incident started when he turned on his blinker to change lanes in traffic. Thompson sped up in an effort to prevent him from switching lanes, but Levston said there was so much space between their vehicles that he had no problem changing lanes anyway. When he pulled into a parking lot, Thompson came up to his window and started shouting at him. As soon as Levston began recording the incident with his phone, he said the man started hurling racial insults at him.
