How fast do most people really get going on bikes, on city streets? I'm a fairly in-shape guy (not as much as I'd like), and bike frequently. I use a gps tracking app for my longer rides. I average 13-14 mph moving speed. Going down hills I hit 24-25 mph. But most places, my speed is definitely closer to walking (3 mph) than driving (30++ mph on city streets). And yes, mass & ability to injure. So, given how reckless cyclists clearly are, I'm sure we'd hear about more bike-on-ped injuries and deaths, right? Wasn't the last death about 43 years ago?
This whole conversation always falls down on party lines, and it's frustrating. Yes, I get mad when I see cyclists entering intersections when plenty of vehicles are around. Or biking on sidewalks with lots of peds around. Or being fairly oblivious on park trails, constantly in the way and weaving for no reason. I think David overestimates how much that behavior makes him personally unsafe when he gets out on a bike. At least, in relation to all the other factors that make biking and walking unsafe, it's gotta be pretty far down the list, and if we have XXXX person-hours to do advocacy or education or whatever, I'm not sure getting all cyclists to follow all rules would achieve much in terms of total bike safety. Time would be better spent fighting for real infrastructure and bike-timed lights and laws that make Idaho-stops legal.
Again, not saying an incident like that isn't scary/frustrating based on what 'could have happened.' I just put it in perspective to other
dangerous behavior.
