Google has been testing its self-driving cars on the roads of Nevada for a while now, but last week it called attention to this project in a big way. Steve Mahan, who is legally blind, went for a ride behind the wheel of a self-driving car, accompanied by Google engineers and local police. This technology could have a huge impact on the accessibility of automobiles, making travel by car possible for those with vision impairments, mobility impairments, and older adults with slower reflexes. The technology behind self-driving cars could also make driving safer for everyone, as most accidents are caused by human error.
