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?
This is part of the reason why China is able to keep costs so low, they keep the construction workers they have and send them to work on another subway line.
This is why China has or will very soon have next gen HSR across their whole country, and CA, the 6th biggest economy in the world, will finish a single HSR line by 2040 at best, on older technology then what China will have widespread.
