We EXPECT that just because we drove in the past and can drive today that we will continue to drive in the future.  Any other planning assumptions cannot reconciled with.  Even some of those that get that petro-fuel based transportation system is not sustainable cannot connect the dots so to speak into land use decision making.

I have come to the conclusion that we wont change until we literally run out of gas. Then the masses might just wake up.  

Before gasoline people still had personal transportion vehicles and they needed parking.  There happened to be a bunch of shit in the parking spaces too.

Absolutely correct. Must have been dreadful. In NY alone thousands of deaths were attributed to the spread of infectional diseases by flies around 1900.
When electric trams where installed (don't know about NY exactly, more generally spoken) and less horses were around it was a benefit.
