"Cars taken will be held until fines of $150 to $750 are paid — in addition to a $75 towing fee, a $15 to $20 per day storage fee and a $60 per hour charge if the police officer has to wait more than an hour for the tow truck."
Anyone who has their car impounded is in for a long wait, in addition to the fees previously mentioned. After requesting a hearing, the city can wait up to 45 days before going to trial, accumulating around $1100 in impound fees. An article, with PDF of the recently passed law, can be found here.
A quick Google search yields a partial solution to this issue: plant trees! "If every American family planted just one tree, the amount of CO2 in the atmosphere would be reduced by one billion lbs annually." That sounds like a good start to me.
