Don't even know why taxis are allowed in bus lanes anyway, they are private vehicles, no different to a private car.
Because they are looked on as part of the public transport system and have to pay to get a license. They also have to be maintained to a higher standard than a private car.
Also, it does depend on the bus lane, if taxies are allowed in it. If it doesn't have the word Taxies on the big blue sign, then they aren't.
