“The cost of living accelerates at a far faster pace than inflation. So every year, our costs increase with the cost of living, but our revenues increase at best with inflation,” said @jeffreytumlin.bsky.social.

Enter the transit fiscal cliff.

via @benschneider.bsky.social

Why are so many transit agencies facing ‘fiscal cliffs’?

Covid and inflation played a role. But for many agencies, the crisis goes much deeper.

As a historian, I can certify that we are in the bad times. But bad times eventually end.
In the meantime:
• Figure out a small way to help someone
• Figure out a small way to fight back
• Figure out a small place to find joy
• Figure out a small way to grow and thrive

And do it often.

The purpose of traffic citations is deterrence. A $50 fine is devastating for someone struggling to pay rent, but a minor annoyance to a millionaire. For fines to be effective in advancing safety, states should legalize deterrence-based fines. Net revenue should go to prevention.

In #Switzerland, fine for a speeding driver is based (1) on how far over the limit the driver is going
(2) on how much the driver earns.

One man caught driving his Ferrari at 137 km/h the in an 80 km/h zone in a village near St. Gallen was fined 300,000 Swiss Francs (today, $375,000 US).

Oh good, ChatGPT is getting "erotica for verified adults" later this year

We made ChatGPT pretty restrictive to make sure we were being careful with mental health issues. We realize this made it less useful/enjoyable to many users who had no mental health problems, but given the seriousness of the issue we wanted to get this right.

Now that we have been able to mitigate the serious mental health issues and have new tools, we are going to be able to safely relax the restrictions in most cases.

In a few weeks, we plan to put out a new version of ChatGPT that allows people to have a personality that behaves more like what people liked about 4o (we hope it will be better!). If you want your ChatGPT to respond in a very human-like way, or use a ton of emoji, or act like a friend, ChatGPT should do it (but only if you want it, not because we are usage-maxxing).

In December, as we roll out age-gating more fully and as part of our “treat adult users like adults” principle, we will allow even more, like erotica for verified adults.

Muni's 24-Divisadero trolley includes a 22.8% grade on Noe St between Cesar Chavez & 26th. It effortlessly glides up the steepest known trolley block in the world, fueled directly from Hetch Hetchy hydropower since it replaced the Castro Cable Car line in 1941

Trolleybuses pull power directly into efficient, hill-climbing engines without need for massive, pavement-crushing batteries. Next gen trolleys with in-motion charging offer significant off-wire travel, allowing incremental wire extension. SF and Seattle partnering:

To deliver Montreal's best pedestrianized streets and protected bikeways, the borough mayor in Plateau-Mont-Royal knew to lead with art, community, kids, landscape and beauty. He coordinated department staffs, provided political cover, and created quick results. Still, I'm terrified of this approach

Reminder: Calif's landmark enviro legislation, CEQA, was designed not to advance the environment, but protect status quo. Every project, incl critical projects for climate, can be delayed for years by single cranky person. We need regs that accelerate climate, equity, safety, ag and other solutions.

Gov signed SB 71, making permanent @scottwiener.bsky.social's CEQA exemptions. For much of our transit priority, protected bikeway, Slow Street, etc work, CEQA process would have taken longer and cost more than project itself, and done nothing for environment.🙏
