these are all opinons btw....
GOOD Lights for the rear are not only for your safety, but also kindness to drivers. If they see you and have plenty of time to get over you are both better off than them running up on you before seeing your tiny little $.99 reflector blinky. They may be able to get over... but then leave even less time for the car behind them. Lights bright, and Lights high.
Sidewalk is only used if I am going REALLY slow AND it's empty (waiting on something, getting out of the way to make a call/stop), OR if I'm going the wrong direction. I'll only do that if it's one downtown block, or my last job had a section along the frontage rd to a major hwy... I sidewalked it... don't think i EVER encountered someone else on the hwy sidewalk. I admit... I didn't go slow at that point.
I filter at lights if the line is long enough that I would hold up others from getting to the light. In that case, I split the lane or take the right until I reach the light, or the traffic starts moving... then move into place in traffic. NEVER enter an intersection next to a car. My reasoning.... I can get through a light without holding up cars.... but if I'm waiting far back in line, I would more than likely make cars miss the light because they are stuck behind me. I can do the 25mph that it take to clear the inersection (usually faster than cars)... but I can't do the 35-45 that it takes to make the light from the back of the pack without holding up cars.
For the record... there are various laws, and strong feelings for and against this. I don't care... that's how I ride. And when I'm in a car... I speed too. so ha!
