I posted a link to a definitive study in a different thread. I'll try to find and post on this link.

Riding more then offsets the risk of crashing with health improvements.The study doesn't take into account a few riders who make up the vast majority of fatalities.
1) rider is drunk
2) rider is riding wrong way (salmon)
3) Rider is riding on sidewalk
4) Rider is riding on sidewalk wrong way
5) rider is riding at night w/o lights... (ninja)
6) no helmet#1 is about 50% of fatalities alone.

Most fatalities have multiple characteristics... And these apply even when a driver is found at fault.OP is definitely correct in that MUPs have higher reported accidents and ER visits but lower fatalities.

Other poster mentioned fatalities usually at intersections! People presuming right of way, vehicle not respecting. Unfortunately, a lot of kids are represented here...

Last motorcycle crash taught me at 36 that I just don't bounce as well as I used to. I stopped for red light car behind me did not... Now that I'm 48, I really don't want to test that. I respect the OP's position and envy his infrastructure.

I try to commute once a week. 11 miles of country road, 8 of nearly empty MUP and 2 of upscale neighbor hood, but 5 of high speed parkway and heavy urban traffic. Of the traffic area is a "favored" bike way per city. I agree. I only get nervous a few places, and most people have worse...
