a) reduce road and parking space in order to encourage better forms of transportation ,
b) reduce our consumption of natural resources
,maybe we need to discourage individual ownership of 3000kg utility vehicles?
Because of the increased demand on raods, reducing road space probably won't happen. When cars can get to and from parking spaces by themselves, parking space can move into central towers or edge lots, but the number of spaces is probably going to increase, not decrease.
We all want better forms of transportation, but there's a lot of disagreement about what's better.

I don't see that happening. SUV's and pickups are so popular in the US because most cities are more similar to Houston and LA than NYC or Chicago.
