Let's assume that they can be there one day, say $1 per rider with 1.2 B riders in a year.
And that implies a $0.05-$0.1 profit per rider??
Let's conservatively say the profit to be $.01/rider and that's totally $12 Million profit, not to metion the huge growth potential in ridership! What if it is not $0.01 but $0.1?
