Myeah not entirely an unfair comment.

But I’ve worked in Switzerland and literally it’s even simpler there. You start and app, you say “I’m starting a journey”, you climb onboard and when you get off, you indicate on the app that the journey has completed. You are then charged the cheapest for a journey from your A to your B.

Still inspection onboard, eg if you sit in first class with a second class tracking ticket, but it’s a two-click operation.

Fairtiq it’s called. Pretty neat.
