Cycling most unhealthy form of transport.

"I walked, cycled and drove down Brompton Road in Knightsbridge, one of
the busiest and most exclusive shopping streets in London.

One monitor measured PM2.5 - in a congested London street, most of this
pollutant would be from vehicles, especially diesel.
The other measured black carbon - the sooty emissions from diesel engines.

I spent around 30 minutes on each mode of transport and the broad
findings were these: for black carbon the highest level of pollution was
whilst on a bike, followed by walking, with the lowest level while driving."
