As I was driving on Bethany Home Road this morning, a driver in this A/C repair van darted in front of me from the frontage road just east of I-17 and then stopped and would not go. As I tried to pull into the left lane to drive around him, he cut me off again, then stepped on the gas and ran off. I called the number listed on the Better Business Bureau website and he claimed to be Dave Wolf the owner. He did not appologize. This is very unsafe and rude driving behavior and people like him are the reason why there is road rage, because they cause it. The sun was still low and shining through my windshield so I didn't see him until he cut me off. After slamming on my brakes and honking the horn I waited for him to continue going. He would not move, he continued to just sit there and stare at me. I kept waving him on, but he would not go, that's why I tried to get around him when he cut me off a second time. There's never a cop around when you need one.
