A fed-up London cyclist has resorted to blasting an air horn at unwitting pedestrians to make them get out of his way.
The man posted video of his exploits on YouTube, showing pedestrians jumping in fright and in one case fighting back, nearly knocking him off his bike.
"I am fed-up with people walking in the cycle lane in London. It's like they don't even care that is there," he wrote.
"I decided to make my presence more known by investing in an air horn. These are my results."

Not everyone was pleased with the man's exploits, and many commenters pointed out in some cases he didn't actually have right of way.
"Most you are in the right but the one at 45 seconds is a shared space with pedestrian priority. Don't be that arsehole," one commenter said.
"Doesn't yield to pedestrians crossing the street, honks anyway," another person wrote.
