As a motorcycle rider, lighting has been an issue. Here in California we are allowed to lane split which is also risky mostly because drivers in cages don’t see the bike coming past on the line when they try to quickly change lanes.
Bikers have to be vigilant and as a rider I cringe when I see a fellow really hauling it between cars. Even in rush hour drivers are that much more frustrated with traffic they try to cut over to the next lane quickly without thinking that someone on a bike, maybe not even speeding but fast enough relative to the other cars that in a second or two puts them right in their blind spot. You think the next lane is open but by the time you move a bike is right there at your rear quarter panel. Daytime is worse, not sure if lighting will help. At night lighting would help.
Another safety item I added was a very loud 80 dB horn. Stebel makes them. You have to wire in a switching relay. The normal power to honk the OEM horn closes the relay and routes almost 10 amps to the air horn compressor. It saved me a few times from huge pickups that tried to merge into my lane without looking. The driver will need to do laundry after that encounter, but it sure beats getting run over.
Another new hazard I encountered in Mira Mesa was muslim women wearing an oversize hijab. Their peripheral vision is blocked and they often make lane changes without making an overt effort to look well over their shoulder to clear the hijab impaired view.
Splitting lanes is stupid, unless traffic is stopped or crawling..
The big killer with MC’s are intersections...Major death traps.
