Makes Sense, Within Limits

In Foster City this intersection next to an
elementary school forbids right on red
at a specific time on weekdays.

At crowded intersections making a right turn on a red light is sometimes prohibited, but at least 50 cities have banned all right-turns-on-red within city limits. From the San Jose Mercury News:

Washington, D.C. just passed its Safer Streets Amendment Act, which will ban all right-hand turns on red by 2025. Part of the Vision Zero initiative, it was adopted by 50 other cities, including Austin, Texas, Lansing, Michigan, Philadelphia, Portland, Oregon, and Savannah, Georgia.

Has there been talk of this in the Bay Area?

A: Right turns are prohibited on red lights at several intersections in San Jose, usually to improve safety for bicyclists in locations where protected bike lanes lead to an intersection, or when poor visibility makes right turns unsafe.

San Jose data do not suggest right turns are a frequent cause of fatal or severe crashes. The top known cause of such tragedies is speeding, which caused 21% of severe crashes between 2017 and 2021. The next most frequent causes of severe injury crashes during this period were red-light running and unsafe turning movements, at 7% each.

...the city is also tightening right turns at many locations by using temporary or permanent “bulb outs” at corners. Bulb outs make drivers slow down when turning and give pedestrians increased visibility and shortened crossing distances.

I've seen drivers turn aggressively on red into oncoming traffic and even when there are pedestrians in the crosswalk, and these drivers should have the book thrown at them.

But even a well-intentioned driver must now deal with bicycles and scooters who come up behind them in the bike lane, then switch to the crosswalk to take advantage of the "walk" sign. The multiplicity of parties who can enter the interesection under different rules makes for confusion. Changing the law at specific locations is reasonable, but marking the whole city as no-right-on-red strikes me as more a product of anti-car ideology than common sense.
