A cyclist can travel about three miles on the energy of one egg.
A person walking would require three eggs to go the same distance.
A loaded bus requires the equivalent of two dozen eggs for each person it carries three miles.
A train requires the equivalent of three dozen eggs for each person it carries three miles.
A car that gets 12.5 miles per gallon requires the equivalent of seven dozen eggs to carry one person three miles.
Even if you double the miles per gallon and double the occupancy a car will still use the equivalent of twenty-one eggs to make the trip -- more than twenty times a bicycle.
