It is impossible to ride in a straight line on a bike, and even more so with an element of side wind. The rider is constantly applying control (bars/leaning) to change direction, even with no wind. My gratuitous weaving suggestion above is for the purpose of communication, on the presumption that a motorist is likely to give a cyclist, who he/she assesses is less in control of balance/direction, more space when overtaking. Because you can't be sure whether or not a gust is going to hit you as the car is passing, in fresh/strong winds to which the motorist will likely be oblivious in his/her metal shell, a rider needs a bit more space. How would you communicate that need,
@Cronorider ? Or are you just relying on them giving you Highway Code space? "Give Cyclists Space- only overtake if you can do safely and give at least 1.5m of space"
