This long-form breakdown from Not Just Bikes on John Forester & the disastrous impact of “vehicular cycling” in US bikeway design priorities since the 1970s is a worthwhile watch.

This is why I tell people to avoid e-bike brands using many proprietary parts & tech. If the company closes it becomes very hard to get replacement parts & maintenance. There’s a reason why most human-power bike brands have been using mostly universal parts & accessories for many decades.

It was bad enough when DoorDash spent $48M on CA’s Prop 22 in 2020, stripping workers of basic labor protections & enabling a gig-labor traffic disaster w no accountability.
Now they’ve decided even poverty wage humans are too expensive, to be replaced by an antisocial robot food delivery system.

When I took the League of American Bicyclists instructor certification seminar back in 2011, John Forester’s book was required reading. Even back then I knew it was BS, & I’m glad the League has come around since.
Oh boy, I had the same exact experience as Not Just Bikes when I decided I needed to read John Forester's Effective Cycling before writing about vehicular cycling in my book. It is a truly horrible book, and you really do not need to read it. www.youtube.com/watch?v=pRPd...

If our little town of 14k can do it, what’s your city’s excuse?
I do love that everyone is freaking out about Mamdani and free busses and people talking about raising minimum wage, but I literally lived in Emeryville city in California for eight years total that has free busses AND inflation tied minimum wage since 2007 and it was fine.

Have you wondered why Oakland's protected bikeways on Telegraph, 14th St, & elsewhere are so narrow? The fire department's insistence on 26' road clearance is the reason. Another proposed protected bikeway on Lakeside btwn 14th & 17th was cancelled altogether.

Fire staff want to protect wide open roads to speed response. Safe street advocates want rules that allow for speed bumps and protected bike lanes that slow traffic for safety.

Clipper 2.0 is going to revolutionize how we get around the Bay. Something as simple as taking the bus to the train will be rewarded, not punished.
From my house in Berkeley to my friends in the Castro could be literally half the price as today.

This is way closer than I’d like it to be but Charlotte appears set to unlock an absolutely massive infrastructure plan with the 1% sales tax increase with billions for public transit and roads up by just shy of 8k votes with almost all precincts in.
