It's not entirely clear if Maven will welcome cars from all automakers, but it sounds like at least some Ford and Tesla models will be. In addition, GM will open the platform up to micro-fleet entrepreneurs and will also expand it to Canada and other international markets. By doing all those, the company is hoping to make Maven much bigger than it is today, with a lot more and diverse vehicles on offer. Steyn said: "If, at some point, there's a UFO that you want shared and you want to be on the platform and it's going to do a job for somebody, we'll be able to put it on the platform."
