When we arrived in Chicago nearly ten years ago, the cab fleet was almost totally homogenous. If you got in one, it was almost definitely going to be a Crown Vic. Over the years, a few Prius (should that be Prii) started to show up. Now the a Crown Vics are becoming a minority as newer vehicles that are predominantly hybrid take over the fleet. Having slightly smaller vehicles makes a lot of sense given that there are often few occupants. However, as I walked home the other day, I passed the lone of taxis outside the IBM building and the car at the front of the line caught my eye. A Ford Fiesta! Now that really is a shrink!
