The US state of Arizona, where many companies have already tested driverless cars on the roads, has decided to invest in establishing a massive purpose-built proving grounds for autonomous vehicles. 

TheState.com reports that Arizona Governor Doug Ducey has signed an order which establishes the Institute for Automated Mobility.

Details such as how much area the facility will cover have not yet emerged, but it’s reported that numerous public sector organisations and private sector companies are partnering on the project.
