We knew it was just a matter of time, but sure enough, there in our inbox this morning was the first announcement of an online petition begging D.C. Mayor Adrian Fenty to change his mind about the $4 taxicab flag drop fee.

A group calling themselves D.C. Residents for Reasonable Taxi Fares claim that the fares proposed by Mayor Fenty will mean that taxi fares in D.C. will be the highest in the country–higher than New York, Boston, Philadelphia, and Los Angeles. They also point out that taxicabs in Arlington have a $2.50 flag drop, which could lead to confusion, and decry the continuation of additional rush hour fees when customers will also begin paying $.25 a minute when the taxi is idle in traffic.

So how much more would the Mayor’s $4 flag drop actually cost D.C. taxi riders? Washingtonian spent a little time calculating the differences for a handful of average trips and found a mixed bag — some trips, like from just below Dupont Circle to Georgetown, would end up being cheaper, though many others, including one from Dupont to Union Station, would end up being several dollars more expensive.

The online petition can be found here. Will you sign it?
