A sales rep at a local Chevy dealer pointed me to a website that collates mileage stats for Volt owners (he owns one). There's a separate tab for Bolts. It uses OnStar data. I signed up and now it collects my OnStar data for the site. It's a neat way to see how much folks use their EVs. If you own a Bolt already, sign up and increase the size of the membership pool. Larger numbers mean better data about use, location, etc. If you're in the market for a Bolt, sign up when you get it and join the crew.
