While engaged on the never-ending task of photo sorting, I came across this souvenir of my trip to Norway last year. Yes, Oslo's public transport system offers a guarantee: if you're more than 20 minutes late, you'll be offered compensation to cover the inconvenience.
Being delayed for more than 20 minutes is, sadly, not at all unusual in Sydney or other Australian cities. I recognise that public transport systems are already short of funds and that Oslo's system is somewhat less extensive (the nearest comparable city in Australia in terms of size is probably Adelaide). Nonetheless, I can see some merit in the idea. We get compensation in the form of free travel days occasionally, but actually compensating people for expense and hassle getting taxis when services fail could be helpful. What do you think?
