The kiosks could also be used as know transport points. A common place were the ride share community or anyone transferring to another mode could wait for pick up or drop off and then continue their journey. Scooters, bikes, private vehicle drivers and more might be nearby to provide services.
I was thinking you could fund your account and as you used bike share or lndygo or any of the other services the app would debit your account. You could even add Yellow cab, Uber and Lyft if they would want to play along and why not the Parking space company too in case you’re driving your own car downtown and then decide to public transport from there.
