I&#x27;ve always thought trucks should have their own lanes due to very different acceleration and lane changing patterns from other automobiles.  I wonder if the emergence of driverless vehicles ends up leading to a separation of driverless and driver roads&#x2F;lanes.  At least early on.  It could assuage safety concerns of mixing both modes, and one can imagine efficiency gains from chaining driverless vehicles in &#x27;trains&#x27; on their own lane.
