I haven't found the actual bill yet so I don't know what it actually says but this seems to be the case.
The bill is literally linked in the summary. I'll link it again here: https://assets.documentcloud.o...
It's a page and a half of actual content, even with the narrow columns and oversized font they use for whatever reason.
This is actually part of a standard practice in traffic engineering called traffic calming.
It's well known that without strict enforcement people will drive whatever speed they feel comfortable on a road regardless of the posted speed limit. This is why for example when you have a four-lane divided highway with a speed limit of 55-60 MPH (common in most major metro areas) the average speed of free-flowing traffic is still likely 65+.
The same applies in areas where you really do want people driving slower. If you put a nice wide four lanes plus suicide lane down the middle of a neighborhood it doesn't matter if you put a 25 MPH limit on it, people will still tend to drive it at the same speed they would any other road of that size. Traffic calming is the practice of intentionally doing things that make it less comfortable for drivers to travel at speed, thus reducing the average speed naturally. Narrowing lanes, removing markings, the funky markings some countries use, center islands, chicanes, etc.
This is the sort of thing that should be encouraged, because they're doing it right rather than just tossing up unrealistic speed limits and going hardcore on enforcement.
Of course that is all on the assumption that these are areas where reducing speeds is legitimately desirable, as opposed to places where some idiots suddenly decided a road that's been there for years is a dangerous menace around the time their kid started walking or some old bastard whose reaction times aren
