Also true in many cases in Europe.
You can get a flight ticket for under 20€ between Germany and UK (RyanAir), and have to pay tenfold that for a train ticket.
Or a 30€ ticket to Romania per plane. Booking a train to Romania is much more difficult and expensive and also easily over 100€.
I would wish that train tickets are cheaper than plane tickets, but if you cross country borders, booking train tickets becomes expensive and difficult in Europe.
You are using acts by Bavarian police to say that acts by Berlin privacy officers are sinophobic.
