One thing I don't like about them is their websites. While the iOs and Android apps work quite well for finding a car, the websites were obviously designed not only for already registered users who want to quickly find a car, but also for prospective customers, press, investors etc. They contain a lot of clutter and the DriveNow website does not even make an attempt to determine your current location, so you have to zoom and swipe the map manually every time. Especially irritating since you want to reload the map repeatedly sometimes when on the hunt for the closest car.
After getting annoyed with their websites once too often I decided to do something about it.
