Erm, the "research". It has nothing to do with viruses and spreading, it was an aerodynamics? piece which was released into the public domain without proper peer review and even the author has admitted does not relate to the spread of viruses or ever intended to. In other words: #fakenews.
As for inconsiderate cyclists: just go into a supermarket. The chaverati are still behaving like er, chavs: pushing past, leaning across, coming back down the one way aisles and generally not giving a shit. And when they get outside they wander all over the pavements, meet their mates for a fag and get in their cars, speed off and continue to dangerously close pass cyclists.
A few ignorant cyclists is the least of your corona worries mate.
