That sounds kind of a you problem. No really, your service being laughable doesn't excuse Germany's service being bad. 10 minutes of delay is unreliable when people use it as their main way of transport, the US is car centric so these delays don't impose the same kind of problems on the general populace.

In Spain our train performance varies wildly through regions, and in some people just don't use trains because they don't work, where in others 5 minute delay is unacceptable. Trains, Buses, Metro, if Google maps makes a mixed plan and it doesn't work because of an unnanaunced delay, I will be rightfully pissed.
