This law wouldn't reserve a specific spot for pregnant women. It would simply give them a placard that allowed parking in "no standing" or "no parking zones." For the most part, it would be parallel parking on the street.

There are already a lot of special parking placards; I marvel at how often "emergency blood delivery" is required on blocks nowhere near a hospital.

I do look out for pregnant women and parents with small children on the subway, and will gladly give up my seat to help them.

Much as I hate cars, I can understand why someone in late pregnancy might avoid the subway. Some stations are deep and there are multiple flights of stairs.
