What make me laugh is people who DON'T use bus lanes when they SHOULD ;-)
The trouble is that there are so many variations in the times and
authorise vehicles for the bus lanes that it gets very confusing, even
for us professionals. There are some lanes in the city where taxis are
excluded, even though we are allowed in nearly all of the others.

I try to use them when legal, but if you don't know the road it's a
significant distraction having to read the rules for each short section.

And, as someone else said, when they are legal there is invariably
someone, or several someones, parked in them!
