&gt;The demonstration in Europe shows that driverless trucking is right around the corner.  The primary remaining barriers are regulatory. We still need to create on- and off-ramps so human drivers can bring trucks to the freeways where highway autopilot can take over. We may also need dedicated lanes as slow-moving driverless trucks could be a hazard for drivers.<p>So, right around the corner except for billions in infrastructure investment.<p>I&#x27;m quite certain that this--like many other things related to autonomous vehicles--will happen. But they&#x27;re decades further away than 75% solutions lead many people to think.
