Is the comment I got from a not so friendly pedestrian chap on Regent's canal near Mile End (London)
On commute to work, the guy was walking under one of the canal briges.
So I hit the disk brakes of the HP Speedmachine, which stopped promptly as expected, about 3 meters from him and still outside of the tunnel... Not sure if he got scared, but he gave me a long dark look and made this comment about me being lucky to be alive.
I tried to explain the bike was quite safe, but he cut me short from the start saying he had more important things to do than talk to me and so we parted company in bad terms.
Sigh.
