The common thing they’ll say after an accident is “the bike came out of nowhere”. Well it didn’t, did it? We don’t live in the Star Trek universe. It came out of somewhere – it didn’t materialise on your bonnet.

Be too cavalier with brisk overtakes. I’m a big fan of them, but bear in mind that other road users will react much better to something they expect than to something that comes as a surprise.
