While 1 million miles sounds impressive, it's probably not more than any of the big OEMs has done so far. Every car manufacturer is working on self driving cars, plus some others (Waymo, Uber, Continental). The difference is that manufacturers don't talk that openly about it. They are used to keep advances secret until you can buy it. I'm sure Daimler, VW, GM and Ford test with a similar fleet. If they come to market at the same time as others they'd need to find a manufacturer that doesn't already offer it. If they want to be first they need to beat manufacturers that have recognised the risk and can spend several billions a year without making a loss..
