but would suggest that bikes, (by their nature of being generally faster, harder and heavier than people, and used on the public roads), should be treated differently. and regulated, as we do with other vehicular traffic.
Bikes are classed as vehicles under the road traffic legislation, so they are regulated in the same manner as cars, etc.. Further regulation isn't required, enforcement is.
Debates like this always just turn into motorists versus cyclists, private motorists versus versus taxi drivers, cyclists versus pedestrians, etc., with each side claiming to just have people's best interests at heart. All it serves to do is divide the population into groups to have a go at each other and distract from coming together and forcing the government to actually do something about it. As a population, our adherence to road traffic legislation is poor, and many seem blind to their own transgressions while being acutely aware of others (not calling out anyone in particular here, just always how these threads go.)
To focus on injury or damage caused by cyclists or pedestrians is to ignore the cause of the vast majority of such damage and injury on our roads. So we get stats like the 111 people killed or injured by cyclists across the whole of the UK (a pro-rata rate in Ireland would be 8 per annum), yet the reports showing 3 cyclists a day being hospitalised in Dublin are largely ignored. Likewise, when Dublin Council release figures showing ~90% of drivers in residential areas break the speed limits, no one bats an eyelid.
The insurance argument is also somewhat misunderstood as well. How many motorists don't end up out of pocket dealing with damage caused by another insured driver? It's more than 10 years since I commuted by bike, but last time I was knocked off I was told I'd have to take a civil case against the driver if I wanted to claim for any damage to my bike.
As someone who commutes by car, I'm glad of the cyclists on our roads, because I know on the wet days where their numbers fall, my commute will be a lot longer. That said, I do wish they would obey the law, but I know that focusing on them as a group isn't going to do much for our overall road injury or death rates.
