Wow things have changed in Melbourne in the last few years since I lived there if people love the trains, now. When I was in there everyone bitched and complained about the trains every day.
I would have expected this meme to have a tram in the top panel and a train in the bottom. The bus wouldn't have rated a mention.
Funnily enough it's the cars that make buses bad. Buses are slow due to the traffic and car centric road planning.
They're also so damn infrequent they're useless (I have a bus stop right outside my house I never take because it goes every 20 minutes at it's most frequent. 40 minutes to an hour otherwise...)
