Vigilante Justice?

I was biking home tonight, approaching the Queensburo Bridge, and "noticed" an expensive car driving erratically: taking up two lanes, sliding between two lanes, and otherwise making me very nervous.

At a red light, I pulled up to the car and confronted a young woman, not at all surprisingly, gabbing on her cell phone. Not only is this illegal, it's dangerous.

[I would add that since the hand-held cell phone ban, drivers have gotten noticeably less erratic.]

I loudly (her window was up) but not really rudely yelled at her to stop talking on her phone because she was obviously distracted and could kill somebody like me.

She smiled at me and gave me the thumbs up and continued to talk. I insisted she stop talking on her phone. She put her cell phone on her lap and I started to bike away. But I knew she hadn't hung up. So I came back to her window and of course she was still on the phone. I again asked her to stop. She gently waved and even kissy-kissied me, but refused to hang up.

At this point, in a moment I would call inspired genius, I leaned over, took the cap off her front left tire, and proceeded to release the air. To be honest, deep down I've always wanted to do this, but that's not really the point.

I figured if she has too oblivious to notice I was letting the air out of her tires, she really shouldn't be driving. Before all the air was out, the light changed and she gently rolled away. She could still drive on the tire, unfortunately. But it definitely needed air.

While the Indian limo driver behind her gave me a stern nod of disapproval, I believe I did the right thing, like trying to take the keys out of the hands of a drunk driver. Or am I just an asshole?

I am interested in your comments.
