Toyota will test self-driving car "edge cases" at new proving ground in Michigan

Toyota announced today that it will build a gigantic, 60-acre facility in Michigan to test "edge case" driving scenarios with its autonomous vehicles that are too dangerous to perform on public roads. The news comes more than a month after the Japanese auto giant halted its self-driving tests on public roads in the US in the wake of a deadly crash involving a self-driving Uber in Arizona. Construction permits were filed this week to transform an approximately 60-acre site at Michigan Technical Resource Park in Ottawa Lake into a closed-course facility for the Toyota Research Institute, the car company's Silicon Valley arm, to test its vehicles. The site will include congested urban environments, slick surfaces, and a four-lane divided highway with high-speed entrance and exit ramps. When it becomes operational this October, the company will use the site to specifically test scenarios deemed too risky for public roads, most likely involving vehicles without a human driver.
