Asking once a day at app startup, if the car is stationary, would be fine.
But covering the navigation screen every few minutes is a safety hazard, as well as a UX disaster.
People glance away from the road to look at Waze. For safety, these glances must be kept as short as possible. When the carpool signup screen is blocking critical navigation data, the user may not only miss a turn, but will also have to spend time to remove the screen, which requires more attention turned away from actually driving the car safely.
Please find a better way to do this - nag not more than once a day (its fine to be able to deliberately summon the signup from a menu on demand, and then only if the car it stationary.
