It’s like any modification, you just inform the insurance company, it’s then up to them to decide if they want to provide cover. I saw an interesting article recently about the amount of data that Police forces recover from vehicles in the event of an accident, it’s mind boggling (maybe for a separate thread if Mab hasn’t covered it already).
There is an occasional TV series on BBC (linked below on iPlayer) that sometimes shows you the amount of data Police accident investigators can download and recover from modern cars which is stored in the vehicles ECU and various computer 'brain' modules. A bit like the 'black box' Flight Recorder fitted on aircraft. They can record things like the speed of the vehicle before any crash and on impact, how, when and if the brakes were applied, driver steering inputs, etc.

(An 'old school' method of seeing if the brakes were applied during a crash was to examine the filiments in the brake light bulbs, if they were lit the hot filaments in the bulb would be distorted by the force of the impact. I guess that no longer applies with LED brake lights!)
