There is a rebellious group of Parisians who know how to travel
by tube with minimal expenses. Instead of paying 1.9 Euro per ride
(or around 53 Eur for a pass), they contribute 5-7 Eur a month to a
joint fund, which covers their fines they need to pay if they are
caught free riding. And RATP transport authorities estimated their
losses to be approximately at around 80m Eur a year. What is known
is that there are only 968 inspectors, and the tube users are
checked only once every 6 weeks. You are thinking about how
profitable it is to do what the Parisian group is doing and what
are the chances of being caught.
