The WA House just approved SB 5501, which prohibits employers from requiring driver's licenses as a condition of employment, unless driving is an essential function of the job. It passed 61-36. This bill is headed to the Governor's desk!

I'm not getting worked up about this one at all. I've known for a while that Google Maps invests a lot in localization to the extent of even drawing borders differently based on where a device accesses Google Maps from.

The people colluding to create housing shortages in order to jack up the price of homes and rent are mostly single family homeowners, not nefarious corporate actors; and they’re doing it in public at your local planning commission, not in smoke-filled conference rooms or whatever.

We are thrilled to announce SB 79, a new bill from @scottwiener.bsky.social that will legalize multi-family housing near transit. We are excited to co-sponsor this landmark legislation with SPUR, @streetsforall.org and the Bay Area Council.

I think there's something to be said about how there's too much process to get infrastructure and housing projects approved, but this seems like a pendulum swinging too far in the direction of deregulation when potentially even safety precautions are thrown out the window.
I made a whole video about how absurd the Vegas Loop is from a capacity standpoint, but this new ProPublica piece is absolutely wild and should make everyone even more nervous about Elmo’s involvement in the incoming administration

Starting to wonder if I should limit my kids from watching certain PBS kids shows like Nature Cat or Wild Kratts. Too many times there are villains that are trying to build homes.

Climate change is real and getting worse, so we're eliminating red tape to rebuild low-density homes in high-risk areas (and requiring insurance sales) while retaining the regulations for high-density structures in low-risk areas and for clean energy production and transmission.
