Sorry but I thought it would be common sense that someone driving into the back of you wouldn't damage a front wheel.
The typical claim culture now days does have everyone paying more for insurance.
Depends on the directionality of the rear shunt. I had a shiny new MK5 Golf 170TDI GT Sport, 2 weeks old and 400 miles on the clock get clipped (hard) by a bus when it was parked up. Although it was a rear shunt, the car was also pushed into the kerb, gouging the front passenger side wheel and tyre.
Insurance companies are to blame for inflated claims generally, not claimants. They're not charities, they get their mark up on every increased cost.
I was pursued to make a personal injury claim, despite not being in the car when it happened, the "legal" cover charged the other side about £470 a week rental for a Golf 1.9TDI Match, and dragged out the repair - after 10 days all the parts (2 new wheels, new front bumper and grille, rear bumper, rear quarter panel, lots of rear axle components) were ready to go, after 5 weeks my car still hadn't been touched, on the legal team's orders. I blew a fuse with the legal team and work started shortly after, taking 2 weeks.
