Sadly, HCH-II's have not been approved for taxi service in my side of the country... mainly because of its "below regulation" small trunk space. Also on the same token neither has the Camry hybrid which also has a trunk as small as the HCH-II.
On the other hand, you go for a 10 mile trip around the city and most of the taxis you'll see are Prius II. Some of the local taxi companies have literally hundreds of Prius II units on their fleet and the numbers just keep growing and growing.
Times are changing and even the die hard pickup hillbillies around these parts can no longer insult hybrids as they used to, since even they will be forced to learn something new when they take a ride in one. Sweet indeed.
