One pet peeve that gets to me is something that's done on a lot of commuter railways and S-Bahns, the 10/20 minute schedule. The schedule looks like:
2:10
2:20
2:40
2:50
3:10
etc, when it should be like this:
2:10
2:25
2:40
2:55
3:10
This minimizes waiting and allows for frequent service every 15 minutes..
What are your pet peeves?
I know a few places that have tap-to-pay and automatically give you the 1 day all you can ride pass once you've spent that much. There's not really a better system unless the transit is totally free. No need to fuck around with apps or even transit cards.
It is the ideal (excluding free). Pay-as-you-go capping with tap-to-pay.
