Are you saying men always felt women’s place was in the kitchen and now women are saying it isn’t so they’ve moved more liberal?
Pretty much, although it's not just about gender issues. Women have turned more progressive on a variety of issues (climate change, the economy, social issues) whereas men haven't.
I don't think it ever applied to emergency vehicles, although I'm not sure about school buses.
Indeed:
I'm not sure if commuter buses include school buses, but you'd expect it too.
The main changes seem to be a reduction in tolls. Which is fine as a starting point, although I hope they increase relatively quickly.
