The cure for that is a trip to the Netherlands. The only helmeted cyclists are a) "road" cyclists racing, training or cycling at a very high speed, b) small children, especially those still in child seats on mum's or dad's bicycle c) tourists, especially the clueless type. 

The most important factors in cyclist - and pedestrian - safety are proper physical and legal infrastructure (making the more "powerful" road user bear the onus, at least in part - a cyclist against a pedestrian, a driver against a cyclist or pedestrian, a HGV (big truck) against all the others) and education for cyclists from a young age. There are tours to the Netherlands and Denmark to study the successful models. Helmets have some usefulness in certain situations but in general they are a diversion from the real issues and yet another way of blaming the victim, not the perpetrators of pollution and road mayhem. 

Your attitude towards cyclists, as well as towards Black people and LGBT people, is all too obvious
