Wait you guys start over I missed the beginning

It is 10:04 Seattle time now.  Sometime in the last 20 minutes there was a fight between a cyclist and a driver and I missed the beginning!

I had just reached the corner of Denny and some other street when I noticed across the way a cyclist in a fight with a guy in a red car.  The driver side door was open and they were really going at it.  The red car was in front of a line waiting at the light.  The cyclist was between him and the center median.  The driver was still in his seat;  I think he still had his belt on.  There was a girl in the passenger side.  At first I wanted to run over there and pull the cyclist off but I was on the other side of 4 lanes of traffic, and I was wearing my backpack with my work laptop.  The cyclist was fucking furious.

Then the cyclist broke off and rode away.  Some lady honked and pointed at the guy in the red car and said something like "I got your number!"  Oh also the guy in the red car like couldn't start it, but that doesn't seem relevant.  That is when I started to wonder...why would a cyclist be that pissed, and why was the guys door open if he still had his belt on?  Given all the clues I'm beginning to think the guy in the red car doored the cyclist, which would mean he deserves much more of a beatdown than he got.  I may never know exactly what happened, unless a police report is filed and I can get access to it.  Suffice to say I spend the rest of my communite wondering how to best assault a person in a car.

Punching doesn't seem like a great idea...too hard to get a good shot in through that opening.  I think the best option is to, when on a bicycle or motorcycles, carry a can of mace on your belt.  If you get doored and survive, you can spray it right inside the car.  That should fuck up everything inside without too much blowback in your face, which hopefully will still be protected by your helmet.

What do you guys think?
