Driverless cars and road trains. Crazy stuff. What’s next, jetpacks? The Where The Sidewalk Starts blog is talking about how Nevada has finalized rules allowing driving permits for robotic cars. And Europe expects to see ‘convoys’ of driverless cars hit their roads by 2020. That’s right, you wirelessly connect your car to the back end of a convoy, driven by a human professional driver in an engine ahead, then sit back and relax while someone else does the driving. Wow, I hate long drives, I’m moving to Europe!
