Since it launched seven months ago, General Motors’ carsharing program Maven has expanded to five U.S. cities, according to a Tech Crunch report.

Currently, it has 5,000 registered members and 4.2 million miles driven, says the report.

Maven customers experience smartphone and keyless integration with the vehicle. Customers use its app to search for and reserve a vehicle by location or car type and unlock the vehicle with their smartphone, says GM. The app also enables remote functions such as starting, heating or cooling, and more.

“I think we’re ahead, when you look at the last year, when you look at Maven, when you look at the investment in Lyft,” Dan Grossman, Maven’s chief operating officer, told Tech Crunch. “When GM sells a car, it’s great for GM. When someone uses a Maven, GM gets a piece of that, too. When a Lyft driver picks up a customer in an Express Drive vehicle in a GM car, we’re getting a little piece of that, too. I think General Motors is really ahead of the curve. Nobody has a crystal ball, but if there is going to be this change or evolution in the automotive industry, it’s nice to have all these options available to a company this size.”

Maven will continue to focus on expanding — in the U.S. and eventually internationally, according to the report.
