I think it would be cool if you could work in integration with Ringo and Paybyphone and similar apps so it's only one button between arriving at the end of the Waze route and purchasing parking time - Waze should obviously be able to recognise the car park based on GPS but can always load it up ahead of time when you navigate directly to a specific carpark - maybe it could warn you about other nearby parking zones so you make sure you're selecting the right place
