... you want them to EVER drive again - after going as fast as 75 mph, obliterating the bus stop where the family was waiting and then suggesting that she didn't understand how it happened? WTF?!? #bikesf

20170809 trucker-bike-recycle-bin-stickers Another trucker bike with a bunch of stickers on its front-loaded bin. Which is a recycling bin, apparently from WM (Weed Management).

A messenger in these parts #BikeSF works with a recycling bin on the lowered front wheel rack (it's a trucker bike).

(I haul 3 recycling bins on my cargo bike, but I use them for recycling. Alas, with no Waste Management Inc. détournement.)

20090719 ss00 fun-cycle-turn · A photo of the "Fun Cycle" making a turn at Sunday Streets in July, 2009. Valencia Street has gone through many changes since then, but Sunday Streets is still going on!

• Bonus #TwitpicTuesday rescue is from my first Sunday Streets in the Mission. This is still going on! #BikeSF

(The previous tweet's tinyurl still works, but it leads to a Flickr tag. Nowadays I have a proper "Sunday Streets" Flickr album at flic.kr/s/aHsjwu17EZ .)

A green Swift Folder folding bike parked on a BART train in 2011, in an area clearly marked "Bike Space" (which was something new back then). Passengers are boarding in the door next to the Bike Space, and you can read the words, "Montgomery Street Station" behind them.

Right before the ribbon-cutting of the "new" Valencia Street bike lanes, an SUV-driver hit a bicyclist. A little later, a robotaxi found the "new" bike lane and parked in it ... then it had to back out while avoiding backing into the crash scene. #HowItsGoing #BikeSF

The first flexpost down from San Francisco's first "protected" bike lane, 12 years ago, after less than a week. #BikeSF #FreshKermit We need something better than these bendy-straw drive-over plastic bollards.

I didn’t realise slow Lake street had so much through traffic nowadays… they really need some modal filters.

Black bike in front of the Golden Gate Bridge.

Black bike in front of the Golden Gate Bridge.

The rain has been nice, but I'm looking forward to the clear and sunny days coming up.

Throw back to a few weeks ago when I was testing out my new Velo Orange cranks set for one of my favorite bike rides across the Golden Gate Bridge.

We have a similar bike lane in San Francisco, an attempt to accommodate car "needs." Twice a week, it's full of dumpsters from trash-collecting, and every day it's possible to park so as to block the concrete. A complete failure in every way. #BikeSF
