Somewhat topically, given recent discussion on other threads, I saw this in today's Worst. If the RAC deal with 66,000 claims annually (I assume this is a nationwide figure but the article doesn't make it clear) and over 30% of those represent a shunt of some form, that makes 22,000 opportunities annually for a rider to be on the receiving end of a life threatening crash. Because, on a bike, any shunt is potentially life threatening. Don't kid yourself otherwise. That's just one insurer. If anyone has any info on relative market share of the big companies, it should be possible to extrapolate that to give a rough total for the number of shunts occuring across the country every year. Then tell me it's unlikely that a rider sitting in traffic isn't under significant threat of being hit from behind. Edit: Rereading the article and taking the information in context, I'm starting to think that 66,000 figure might be for WA alone. If that's the case and we assume that the crash rate is similar across all states (it's not, but this is a very rough thought experiment so bear with me), we get nearer 220,000 shunts nationally per annum. Even allowing for the staggeringly crude, rough order of magnitude nature of my arithmetic, that is a number which should be of concern to anyone who rides a motorcycle and occasionally finds themselves on the end of a queue or in a rapidly slowing traffic situation.
