While this is the goal of the ticket, that is, to have the same effect of a pigouvian tax which is intended to correct an inefficient market outcome, and does so by being set equal to the social cost of the negative externalities, that us usually not the case of a ticket. Tickets only affect those who receive the ticket while a tax effects all. The graphs shows ticket implementation as having the same effect as a pigouvian tax. This is the ideal revenue brought in by ticketing as that is the price burden that will bring the socially optimal quantity. While this is ideal, this is very unlikely to happen through ticketing because, with ticketing, one must factor in the probability of someone receiving the ticket and multiple that probability by the price. The graph does not show this theoretical situation because the data of how often tickets are given for mobile phone use while driving is not conclusive.
