Then they only do these things when they're open (although you can return cars at all times), so too early, too late or Sundays are out.
They also only have one location in the city where you can get cars, and it's usually much further away than the closest car sharing option.
For longer trips (and one-way rentals which are great for moving city) they are still a good option, but if you need a car for an hour to get some heavy tools from the hardware store they're out.
(The other option would be to borrow a cargo bike which is free from the city, but again only when they're open and requires more travel to and from the place.)
