Boston is the latest city to allow self-driving car tests

If you'll remember, nuTonomy is operating a self-driving taxi service in Singapore. The test vehicle is a Renault Zoe -- one of the models it uses for autonomous taxis -- but that's where the similarities end. The Herald says there aren't any plans to offer a similar service in the city just yet. As the publication notes, Massachusetts has become somewhat of a hotbed for autonomous-vehicle research. Currently, Toyota, Audi and local startup Optimus Ride are in various stages of testing their wares.
