Insurance is just like bike manufacturers.
They all have their own data, and evaluate the risks individually. Orange think single pivot is the best all round compromise. Your insurer thinks it knows more about the risks of how Touran drivers drive, compared to its claims frequency on them. It might be a higher risk, but per pound earned, it pays less out in compo.
Young kids drive Yaris’s, and when they have an off, all their mates get “whiplash” these days. PErhaps mature’r Touran drivers passengers are less likely. Small car = Santa Cruz VPP including frequent bearing failure.
