It's not a marketing page, really. I made it. Did you see my vlog? It's too bad it looks so pro... it looks like a real estate developer built it :)
But Senator's Wiener's FAQ answers the question you ask: https://extranewsfeed.com/my-transit-density-bill-sb-827-ans...
he says "First, most cities and towns don’t operate their own transit systems, given that transit agencies are typically separate from cities or regional in nature. Thus, very few cities even have the power to reduce transit service, even if they wanted to do so in order to avoid SB 827.
Second, while communities could organize to fight new transit stations or to reduce bus service, let’s also be real: people already fight transit expansions in their neighborhoods."
