I used my HRH key to get FOTL access last week and while I didn't try it on the same ride twice, it would have been pretty hard for them to know I was doing that.
If they are going to restrict the privilege to once a day, they will have to install computerized card readers at each ride and that, I imagine, will take some time to implement.
