I have advocated that road bicycles have to pass a yearly inspection to prove they are are safe for many years.
Cyclist should pay some road tax for the upkeep of shoulders and such
I am not very welcome in meeting of cycling organizations
To be sure, the safety issues with bicycles are usually less, and are more obvious when something is wrong. Also riders do tend to have self preservation instincts. Ticketing riders of reflectorless bicycles, etc. should be sufficient.
I've seen bikers put drivers at risk on many occasions, and if they're going to use the same roads as drivers do, then they should share in the costs of upkeep and be required to follow rules and regulations on those roads - or else be fined and/or lose their license. One of my pet peeves is when bikers use two-lane roads and take up so much space on the right such that drivers can only pass them by going partially into the oncoming traffic lane. If they stayed closer to the shoulder this wouldn't be an issue.
