The traffic _cannot stop_. Not at all. Anyone who breaks down in an inner
lane and can't manage to get to an outer lane will have their car stay in
the inner lane, causing flow congestion. There won't be enough emergency
repair vehicles and tow trucks around to repair or move the wrecks - this
is
larger-than-traffic-jam volume, over an extended period, and most places
don't
really have enough to cover their inner city area, let alone all the
suburbs
AND the interstates between cities. People won't have had time to tune up
the
family car for a long journey. Thus there'll be a small but steady dropout
rate, which will pile up along the outskirts of the road _and_ the
innermost
lanes, because people won't have time to take care of them in the normal
manner.
