Thecenter of American automobile innovation has in the past decade moved 2,000miles away. It hasmigratedfrom Detroit to Silicon Valley, whereself-driving vehicles are coming into life.

Inabidto take production back to Detroit, Michigan lawmakers haveintroducedlegislationthat could make their state the best place in thecountry, if not the world, to develop self-driving vehicles and put them on theroad.

“Michigan’sdominancein auto research and development is under attack from severalstates and countries which desire toreplaceour leadership intransportation. We can’t let happen,” says Senator Mike Kowall, the lead sponsor of four bills recently introduced.

Ifall four bills pass as written, they wouldrepresenta substantialupdate of Michigan’s 2013 law that allowed the testing of self-driving vehiclesin limited conditions. Manufacturer would have nearly total freedom to testtheir self-driving technology on public roads. They would be allowed to sendgroups of self-driving cars on cross-state road trips, and even set on-demandfleetsof self-driving cars, like the one General Motors and Lyft arebuilding.

Lawmakers in Michigan clearlywant to make the state ready for the commercial application of self-drivingtechnology. Incontrast, California, home of Silicon Valley, recentlyproposed far morerestrictiverules that would require human drivers beready to take the wheel, and commercial use of self-driving technology.
