On 1st Ave you turned left out of a business drive and swung out into the far right lane, causing the person in front of me to brake to avoid hitting you. You could have turned into the left lane but you were apparently too impatient to wait behind the car that was stopped, waiting to turn left. Later, you turned onto SB 4th Ave and sped away. I must admit a few obscenities directed at you escaped my mouth. You deserved them.
