Why did City Commissioner Joseph Duda drive so much?

It's pretty clear by now that Philadelphia Weekly and the City Commission aren't getting along great these days.

But reporter Aaron Kase asks a good question in a recent blog post: Why did Commissioner Joseph Duda use 1,350 gallons of gas in his city-owned car for fiscal year 2010, when the average employee with a city car goes through just 685 gallons in a year?

The City Commission hasn't returned the paper's requests for an explanation.

Now, we're not saying that the $2,680 the city spent on Duda's gas will make or break the city's $3.8 billion budget — and there's no evidence that he's done anything wrong.

Still, it would be nice to know what accounts for all that driving.
