Legislation requiring high-viz clothing (waistcoat or bandolier) and effective lights would surely be uncontroversial and enable the police to, initially, “have a word”.
Some of the anti-cyclist animus is caused by the fright all drivers have had coming across an “invisible” cyclist on a bend, in poor light etc.
(There are, by the way, just as many stupid car drivers as cyclists out there, who do not use dipped headlights and give themselves an extra split second to be seen.)
Other irritations include riding two, even three, abreast. The same legislation could require cyclists to be single file in built-up areas.
The explosion in popularity of cycling is a good thing, but until we begin to approach the facilities provided in, say, Denmark or the Netherlands (50 years?) it behoves cyclists as well as motorists to do everything possible to minimise risk.
