Autoline had an interesting program this week about Maven, and a good bit of it revolved around the Bolt EV. It turns out that the Bolt EV is the most popular vehicle in the Maven Gig fleet, likely because it's the least expensive to run, and that Maven is using its data and Bolt EV fleet to work together with charging infrastructure partners. Maven would like more Bolt EVs and has been promised 2000 more for the next year. Definitely worth a look: http://www.autoline.tv/show/2137
One thing which I found interesting and didn't know about is that GM can authorize your phone to work like a fob. Hence no "pain point" of needing to transfer fobs.
