I think large cities should be proactive on this issue and legislate
that unless there is a specific reason for driving a pick up truck
or SUV in the city, less than 3 occupants, etc, that those vehicles
be disallowed (passing through on the xway not counting).

I agree 200%. IMO NO private autos should be allowed inside of major cities.
Moreover, anyone born in a major city, or who has live in one continiously for
more than two years, should never be allowed to leave, except to go to another
large city via public transportation such as rail. Such cities should be wholly
self supporting with no public funds from outside each city and each should
dispose of its own waste within city limits (no outside dumping).
