I just don't really think something as simple as taking judo classes is really going to do much to tackle a problem that likely started at the socioeconomic scale.
I think a role model of positive masculinity is a good place to start.
In Montreal pedal bikes are $0.18/min and electric are $0.45/min. You can make that much cheaper by buying a plan. I got the summer plan and it works out to $12/month, free for pedal bikes on trips <45 minutes (which all of mine are)
There's very few people who want cars totally out of the equation. I live in one of the most bike friendly parts of North America (Plateau in Montreal) and there's still plenty of car traffic. There are arterial roads where cycling is discouraged, and many local roads without bike lanes but designated one way to discourage through traffic.
Even here, people need deliveries, they need to leave the neighborhood. The issue is the car being the default option, not that it's an option at all.
It sucks but it's necessary. Daily delivery is expensive, and they need to be able to reroute people. The volume doesn't justify the model we're used to. If we want it to survive at all it has to adapt.
This needs more attention. It's the start of a death spiral of expertise in the armed forces. Eventually those trainers are going to retire or leave, and we're not training their replacements.
This is how the pick up artist community started. Be careful what you wish for.
