So my girlfriend and her friend came to the conclusion that cycling is selfish because they saw a bus full of people have to slow down behind a cyclist in the bus lane (cyclists are allowed to use bus lanes).
Now perhaps this could be considered slightly selfish behaviour, but I love how society has completely forgotten about how selfish driving is. No one comments on how all the cars are holding up loads of people in a bus. No one comments how there is usually only 1 person in a huge car.
Just another reason we need to move society away from being car-centric. If we could do this then maybe people will realise how selfish they have all been, driving their cars and taking up space, oil and polluting the atmosphere.
