I'm not worried about making friends, I'm just trying to get from Point A to Point B as fast as possible, and if bikers are slowing me down in my pickup they just better get the hell out of my way.

I'm with AdamDZ. I'm alive because of the strobe function on my Cateye 610. I even had an incident where a car pulled almost into me from an off ramp without seeing my 610. That is the driving dead! I also have a not-as-bright dynamo light with LED, headlight, and stand light. I have Trek rear flashie by Spanninga and an LD1000 from Cateye on flash day or night. The LD1000 has side LEDs as does the Trek. When I figure out the mount, I have a police take-off LED amber strobe for the rear. The whole system gives me redundancy for the times the batteries die on one of the lights. And it does happen.

On a commute you're likely to repeat, even those who don't care about making friends should care about making enemies.

Ooooh yeahhh. My safety is paramount, but sometimes my over zealous practices in trying to achieve that safety can be counterproductive, and actually garner a lower level of safety that I was originally trying to attain.

I guess it depends on individual circumstances too.

My commute is all road in the morning. the only thing I deal with is cars and never see another bike. OK, occasionally a sidewalk salmon. I run flashing so cars, particularely crossing vehicles see me.
My PM commute is 75 road/25MUP. My chances of having another passing bike on the MUP this time of year (it's cold and dark) are at best slim, mostly none. Summer is a bit of traffic, mostly neighborhood cruisers, and I'm not running a light then anyway.

If a flashing light designed to be easily visible makes you an enemy to someone, you were just looking for any excuse to be a jackass anyway.
