you'll notice it by reduced services since that 1000 euros is being moved to public transportation from what it used to be. My guess is that soon you'll see tax rates rise to match the shortfall.

And this is all assuming the public transport will be useful and efficient, instead of being the bare minimum of what is available and chronically underfunded and underrepaired. That stuff is capital intensive and expensive, which bureaucrats will soon find out to their chagrin.
