You're probably right, at the moment. The only way that'll change is if people ask that it change. Personally I think it's pretty offensive that a government would deliberately ignore its own laws and still enforce petty ordinances about something trivial like marijuana possession.
Once upon a time it hard to get anyone to enact a ban on smoking in public places. I think that if people become aware of the many ways these huge cars affect their wallets and their health, it might become easier. At the very least it might get lawmakers to remove the subsidies for SUVs and tax them appropriately - if only as an alternative to banning them from residential streets altogether.
