Location: Line 1 from Porte de Vincennes bound for Bastille station
Given that the majority of those reported for fare evasion under the old approach ended up not having to pay, getting 1/4 to pay on demand is probably better going. I agree that reducing evasion is the big goal and that this should be the measure of success of any such project, but is that the intention of this scheme or is it just to cut the costs of collecting fines ?
There's a whole sub-culture of people that will do anything to not pay fines and avoid the sheriff. Most of those that pay up on-the-spot are probably those who take chances but can't be bothered stuffing around afterwards.
