Sounds outdated then given the prevalence of electric cars which don't idle, and even most combustion cars now shut down the engine when stopped and restart it when you use the accelerator.

Doesn't always. Some intersections, rather than having pedestrians get the Walk when drivers get the Green (thus having the crosswalks alternate), instead have the green light one way, green light the other way, and then have a segment of All-Walk, where the walk signals everywhere go on (and thus, there's a red light everywhere, which perfectly opens the door to the scenario described above).

Is it effective immediately?

Is there anywhere online where we can see the text of the bill?

A ski jumping slope goes down, down, down, and then kicks back up at the end. Yes, it's been going down for a while, but by the time you're coming off the end, things are moving upward. Absolutely nothing near where you were at the top, but you can't deny things are rising.
