In an aero-utopian society,I'll simply drive to the interstate,and while topping-off the tank for the out of town excursion,attendants will attach the trailer for me.With a swipe of my debit card,I've covered my fuel,plus a modest rental fee for the round-trip use of the trailer.
These trailers could work 24-7-365,with a 100% coefficient of utilization.
