waits

Not that rare in California. Off the top of my head: Sonoma, Napa, Mendocino, Santa Clara, San Mateo, Santa Cruz, Monterey, San Diego, San Bernardino, and Alameda counties all have cities of the same name. Seems rare in most other states though.

They’re saying all brands use planned obsolescence to force consumers to buy lightbulbs (from any brand) more often, increasing sales for the whole industry, not one specific brand.

This is how the Phoebus Cartel worked for incandescent bulbs. Every brand was in on it, it wasn’t about improving market share for specific brands.

San Francisco avoids this particular problem by having the walk signal turn on automatically when the car signal is green — no need to hit a button (most intersections don't have buttons at all, and the ones that exist aren't even hooked up to the light).

I don't know if this would translate well to other cities — SF has a very pedestrian-friendly layout with narrow, slow streets , small blocks, and short light cycles — but it works well enough here that it might be worth trying elsewhere.

I posted here and was contacted by the founder of a startup the same day. Got invited for an interview and received an offer a week later. I don’t recall getting much spam from that post.

Nearly all intersections in the US are like this.

Note that cars must stop before turning right on a red, so it’s not a total free-for-all. The stopping forces them to yield to pedestrians most of the time.

It guarantees no cross traffic. Turns are still a threat.

I’ve seen the type of light you describe (all pedestrians walk in all directions at once while all cars have a red) in the US but they’re exceedingly rare. In cities there’s always pedestrians and cars waiting in every direction so it would be too slow to be practical.

You pasted a quote from another thread.

A "billion" is 10^9 in the short scale and 10^12 in the long scale.
