My bike got knocked over while (legally) parked at the shops today by a car that took off without leaving a note. However, someone saw it happen and left the car's rego number on my bike. The damage is standard and minor - scratched bar end, exhaust, and mirror. On one hand, it's damage that will cost me to bring it back to its previous condition... on the other hand is it worth the hassle and will it affect my insurance rating? Would you chase this up through insurance or let bygones be bygones?
