I was on my way home from work. The road I drive narrows from two lanes to a single lane in S/E Aurora.

While its two lanes I'm a bit in front of a motorcyclist in the other lane.

When the lanes merge, he speeds up and gets in front of me. He proceeds to drop about 5 mph below the posted speed limit. For a bit he keeps looking over shoulder at me making some hand gestures. He figures I'm following too close or so I gather.

Now I'm a long time motorcyclist myself. Having been riding for over 25 years and still ride to this day. I'm ALWAYS cognizant of motorcyclists.

We approach a stoplight with a group of vehicles and stop for the light. He puts the sidestand down, gets off his bike and starts walking towards my car, yelling and making all kinds of hand gestures.

I'm taken completely off-guard by his actions. I put my hand on my G27 and just barely roll down the window.

Now alot is going through my mind in micro-seconds. I look in my mirrors to see if there is a way out. Nope. Car and another bike to my left, curb/sidwalk trees to my right, car behind me. I'm not getting out of my car as I don't want to escalate the situation.

He reaches the hood of my car and is yelling at me and talking to the motorcyclist to my left (who just happens to be there). While I couldn't hear what was being said between the two, he flips me off and walks back to his bike.

Light changes and he takes off and I make my planned turn...

What I wonder to this day is; Depending on the scenario what action would he have to have done for me to actually shoot him?

IMO, if he pulled a gun, then I believe I would be within my right to shoot him.

If he walked over to the window, punched it out and tried to pummel me would that have been okay to shoot him OR step on the gas and nail his bike and put space between us?

Fortunately I didn't have to play out any of those scenarios but it was probably the closest I'd come...
