It's no shock that GM is taking action while the ink is still drying on bill signatures. GM's driverless car efforts have been frenetic in 2016 -- it started out by partnering with Lyft on a self-driving car network, and began testing autonomous Bolts in Arizona and California mere weeks after it bought Cruise Automation. There's a lot of pressure to act, as well. Its Detroit rivals Ford and Fiat Chrysler are hustling on their own self-driving projects, and it knows that Tesla could eat its lunch if it's not careful. Simply put, GM needs to test on its home turf in Michigan if it wants to remain competitive.
