Speaker4: Yes, I read yesterday, very interesting
Speaker2: high time for this kind of things
Speaker3: what do you mean?
Speaker2: if we want people to use less cars and care about the environment we have to change
Speaker2: to public transport
Speaker2: and make it competitive
Speaker2: so people would prefer to use it than spend money on cars and gas
Speaker1: I find it very interesting as well, most of all I'd like to know if it's doable
Speaker1: I mean it's expensive to maintain the system
Speaker4: But it seems that Luxembourg is not the first to do it
Speaker1: really?
Speaker4: I read about Tallinn some time ago
Speaker4: let me find the thing
Speaker2: I've googled it, it seems that Tallinn did it 5 years ago
Speaker2: and it worked so well that they want to make all public transport free in the country
Speaker4: wow, that's very progressive
Speaker3: let's see, but the idea seems to work
Speaker2: yes, it does!
