Cool isn't "functional"
It's something preservationists forget ALL the time.
Just because something is cool or historic looking doesn't mean it's functional, usable, profitable, safe, etc.
Example, a stone home from the 19th Century lacks modern insulation. plumbing, windows, roofing.
TO salvage it would be more expensive than building a much larger modern homes, hence why they are normally converted to museums than livable residences.
Modern structures like ABC or City of Phila's Police HQ were designed by architects normally for looks and not function.
Many AIA award winning buildings are hard for the people to actually use in Philadelphia (Like Richards Labs and Skirkanich Hall which is a disaster as a functional building but revered and protected by architects)
Or the building was designed for a purpose that's no longer needed and requires a massive expense to renovate (30th Post Office, the failed JFK conversion at the base of South St)
I'm not seeing all these supposed bikes in all these million dollar bike lanes.
