supposing i swerve to avoid a cyclist who has just pulled across in front of me, and in doing so collide with another vehicle or pedestrian. the cyclist has caused the accident, but i would have any claim that arose made against me and my insurers. plus any damage to my own vehicle, loss of earnings, etc. could financially cripple me, all because some bike rider wasn't insured.
Well, the law would say that you were driving without due care. When driving around in thousands of kgs of steel, at elevated speeds, the onus is upon the driver to keep everybody else safe, and this means driving to the conditions. People on bikes are usually only a few kilos and on flimsy bike frames doing
If I approach a cyclist, or other vulnerable road user while I am in the car, I slow down, I expect that they may change course suddenly or without warning and I wait for a safe place to overtake.
As I said before, Used as transport, riding a bike does not present substantial risk to people or property, which is what compulsory insurance is designed to mitigate. If you drive carefully around vulnerable users then you probably will never have a problem.
However, if you do find your car damaged by someone on a bike, their home contents insurance, bespoke policy or, if they were on their way to or from work, maybe their employers insurance.
The point is that people on bikes are not considered hazardous enough to others to warrant compulsory insurance, and this is well documented by various sources. Cyclists are more or less considered as pedestrians by law, so if you want compulsory insurance for them, you will also need it for pedestrians, people pushing prams, etc.
Moreover, how will this be enforced? Will my 8 year old niece need compulsory insurance? What if she lends he bike to her mate?
Cheers,
Nick.
