A percentage of the fare is marked to herd ants. I know the numbers are not correct but for arguments sake let's say Lyft takes 30% of the fare and 5% is marked to get you to jump thru hoops. If you logoff for a couple of weeks, they have already collected the monies and have to try and get it back to you before the end of the period. The hurdles and hoops get easier because of it. It's tactics for ant training.
