I guess you could always give her the facts? ie. there was no fault with her car and instead cause of death may have been due to phone distraction? (as per coroner's report).

As Amalgam said, they all cheat and game the system. I agree this is a potentially bad case of it, but damn I'd still rather have a diesel that doesn't comply in some parts of the world with emissions than say the Toyota acceleration issues that were reportedly responsible for 37 deaths that were covered up.

Each to their own I guess.
