The lowest paid are often priced out because of the people on the road with no insurance. Ride with no insurance and you're just making the entire situation a lot worse. Back in
2004 the BBC quoted someone saying it added about £30 more onto everyone's premiums, so i'd guess it would be a lot more now.
As a biker you should know better, and it's a shame you would even joke about riding without insurance. Us bikers are the most vulnerable people on the road. Having had the heartache of having my best mate killed in a bike RTA, I can not begin to tell you how important insurance is for everyone.
If you can't afford insurance, stay off the road. Even though it might be expensive in some cases, It's there for everyone's benefit.
