Zipcar sounds pretty cool.
It's a short-term car rental service in certain major cities. They've got it in Toronto.What is it?
I could probably just look it up, but I figured conversation is better
The general idea is that they sprinkle Zipcar locations all over town (which they can do because all the booking and payment is online, so they don't need staff at every location) and you pay by the hour (IIRC), not the day like a traditional rental company, so it's meant to allow urban-dwellers who don't need a car to commute but still need one occasionally for different things to avoid buying one.
They also have a few locations where they cater to business users: a couple of zipcars in the parking garage of a building means that, say, their sales staff don't have to drive their personal cars downtown to work every day just to have a vehicle available to go to client meetings. And IIRC, it ends up being cheaper for the company than paying mileage to staff, especially if they set up a corporate account with Zipcar.
