Because most [[but, alas, not all) of us Detroiters know how to drive at 70 or 80 on freeways that were, after all, originally designed to carry cars at those speeds [[or more). Given the amount of traffic that our freeways carry most of the time outside of rush hours, there's really no reason to go much slower.

As for the parking tickets, I have no idea what you're talking about. Downtown is a ticket-fest most of the time, and used by the city as a revenue generator [[to our overall detriment, in my view). There's a reason why they chose this city for the taping of some episodes of "Parking Wars".
