Good news. Good move.
I really enjoyed working with ASI from a small shop, Velowood, and from a big Performance store. The reps and technicans I worked with did dealer service very well.
Now, will ASI give Performance needed leadership?
Disparities in road crash mortality
Disparities in road crash mortality among pedestrians using wheelchairs in the USA: results of a capture–recapture analysis by John D Kraemer and Connor S Benton, 20 November 2015, BMJ Open
“36% higher than the overall population pedestrian mortality rate”
Conclusions: Persons who use wheelchairs experience substantial pedestrian mortality disparities calling for behavioural and built environment interventions.
“That crashes frequently were attributed by police to a driver’s failure to yield right-of-way underscores the challenges faced by pedestrians who use wheelchairs as they seek to safely using existing pedestrian infrastructure.”
Modern approaches to disability conceive of it as an interaction between physical limitation and social or environmental factors. This approach is reflected in the U.S. through the Americans with Disabilities Act, which requires public settings to be accessible to persons with disabilities — including through safe pedestrian infrastructure — and which favours full community integration for people with disabilities. Prior research has shown that pedestrian safety concerns limit the ability of wheelchair users to fully access their communities, in violation of these norms, underscoring a substantial justice dimension to the disparities identified in this research.

Red Lights and the Idaho Experiment
Running Red Lights
Few things raise the ire of motorists (and some cyclists) more than cyclists running red lights. Yet anybody who has ridden in major cities has seen riders proceeding through red lights. Why do they do this?
Cyclists operate on streets that are designed for cars. The current traffic infrastructure does not work as well for cyclists:
- Many lights have sensors that do not pick up cyclists. Cyclists often wait at red lights for minutes, and the light only changes when a car pulls up behind them. If there is no traffic, they may wait for a very long time.
- Cars travel mostly on big streets with few stop signs and timed lights. Cyclists tend to use side streets where they encounter stop signs or red lights every few blocks.
- Cyclists travel at lower speeds and are less insulated from their surroundings, so they are more aware of…
