Sorry to hear the guy was killed..But!
They should have to pass a Test to cycle on the Road, until the Do they should be confined to cycle routes, If drivers have to share the road with them then very least we should can expect is that the cyclist is proven to be safe on to be on the road like a motorist has to be...why should it be the driver that is always deemed to be at fault just to appease the hairbrained green lobby that thinks that people born with Bicycle pedal shaped feet and a deeply creviced arse are some kind of god.
Ultimately many Cyclists would still be alive today and a lot more uninjured if they had higher standards to acheive before they took to cycling down busy roads, its only fair that they take some of the responsibility upon themselves for their own well being.
