I don't know how the public transportation is in Berlin or Bonn, but I remain pretty unimpressed with it in Düsseldorf. The train schedule is very unreliable; trains and cars share the same road, and the train is regularly held up by cars. It is difficult to buy a ticket because the machines on the train only take coins, do not offer guidance on which ticket to buy, and are regularly out of order. Tickets are not checked before boarding. Instead, they regularly send stealth ticket checkers into the trains and give fines to people that weren't honest or bought the wrong ticket. Many stops are not elderly/wheelchair accessible, and it would take a lot of work to update them. That said, I did move here from Japan, so I have a high expectation. If I had come from the US, I would have been pretty happy just to see that trains exist! Minus the handicap-unfriendliness; everywhere I've been in the US, the bus drivers get out and set up a ramp for wheelchair users when needed.
