First, when making the decision between taking the train or driving, riding a train will improve its efficiency (and if it's almost empty, it will improve the efficiency by an even greater percentage), and if you drive, the total efficiency goes down as there is now an almost empty train AND a car making the trip.

Second, if the occurrence of empty trains isn't more than balanced by the times they are full, they should (and usually do) decrease the frequency and length of trains at the times it is almost empty.

Third, the completely full cars were compared with quarter-full trains already. I would expect trains are over a quarter full far more often than cars are completely full. Heck, I would think that trains are over 100% full (considering standing room) more often than cars are full.
