Not long ago, Leanne asked readers to weigh in on Zipcar vs. City CarShare. The subsequent brand-identification debate was not quite as acrimonious as the typical Mac vs. PC debate, or even the heated Wrangler's vs. Levi's debate we once overheard in the Houston airport.

We're not sure what the above photo means in the context of the car-sharing debate. Are we seeing, as with SF Weekly and the Bay Guardian, a national chain using unfair tactics to crush the local competition? Or does this photo simply show that, again as with SF Weekly and the Bay Guardian, most people don't distinguish between the two companies and even their customers can't always remember which is which?
