They don't want authentic history or authentic modernity. They just want a publicly-maintained Disneyesque nostalgic feel.
Personal cars (mostly of 2000s vintage or newer) are piled in the streets of Beacon Hill. In the interests of historical feel, I say have them all towed away (by Clydesdales driven by Teamsters), never to be parked there again! Personal cars are more ahistorical by the pound or cubic foot than all curb cuts put together. WALKING is historical. Everything should look like Acorn St. There. I fixed it.
