For London Breed and others who say police enforcement is the key to ensure pedestrian & cyclist safety—we just saw an SFPD SUV making an illegal left turn from Mission station on Valencia on to 18th St, while cutting off through traffic. So *they* will enforce traffic laws?

Streetlights and signs are the bulletproof backpacks of road safety. He is unwilling to inconvenience a single driver. This man is not remotely serious about preventing the next tragedy and it is just as certain is the next school shooting.

i’m pissed off that something as simple as a bollard does not get s mention in this article sfchronicle.com/crime/article/…

“A family did what our city needs people to do in order to address our roadway safety crisis and climate crisis: Sold their car and took public transit.

They were living up to the policies the City and Mayor Breed claim to prioritize: Transit-First, Vision Zero, Climate Action.”

It’s important London Breed Board of Supervisors and SFMTA understand these deaths are the inevitable result of the choice to prioritize motorist convenience (and property) over human lives. Offering thoughts and prayers without pouring cement is identical to R cowardice on gun control.

Zach Klein Please sign the petition to close the intersection of West Portal Avenue and Ulloa Street to car traffic: actionnetwork.org/letters/westpo…

This tragedy was preventable, including by closing the intersection to cars, and closing it to cars will also improve the speed/reliability of Muni.

If SF is unwilling to do whatever it takes to prevent the killing of families waiting for the bus, how can we criticize those that resist gun control and only offer thoughts and prayers as consolation?

We could end pedestrian deaths if we were serious.

Ideally SFMTA would close Ulloa in front of West Portal station, and make it westbound only at Lenox. The first block of W. Portal Ave should be pedestrianized, and the current parking and street used to create a park/promenade. Make it a jewel of the Westside.

Did you know Paris has a 5-Year Pedestrian Plan?
- 300 million € to be invested by 2026
- 100 new hectares of pedestrian space
- 100 more “streets for kids”
- New focus on 0 pedestrian deaths #VisionZero
- Longer pedestrian cross times geared to seniors

Does YOUR city have one?

In a move that could be a model for other communities, L.A. voters approved a measure that will require the city to implement the pedestrian, bus, and bike improvements in its mobility plan whenever it repaves a street. 🎉 StreetsblogLA has more.

Huge. All levels of European govt need to act quickly, like Paris has just done, to stop the car bloat before it’s too late.

Once enough people have SUVs the merciless logic of: “I need an SUV too to protect me/my family.” makes it very difficult or impossible to reverse.

Never forget, a 13-year study found that protected bike-lanes led to a drastic decline in fatalities for all road users.

ALL ROAD USERS.

And painted bike-lanes? No safety improvement at all. For sharrows, it’s safer to NOT have them.

It is great to lead the transition from LRU caches to FIFO-based caches!
A lot of interest in our new cache eviction algorithm, SIEVE sievecache.com. It hits the top of HN twice within a week. This happened after S3-FIFO s3fifo.com hit the top last month.

I try to not talk about SFTMA communication as I am 1) not a PR expert, 2) know it's a very hard job with lots of competing inputs and priorities, & 3) staffing is very low right now. But the way the agency is handling Valencia feels ham-fisted. Let's start with some context. 🧵
