annoying people, then you are the biggest idiot in London.

Whether the purpose is to annoy people isn't really the point, but it
certainly has that effect. I don't understand why London has - rightly
- clamped down on users of private cars in the congested area, but has
done little to reduce the volume of taxis on the streets, who cause
far more non-necessary pollution because they're running around empty
for much of the time, quite apart from taking up road-space, causing
noise, et cetera.
