Hm...my initial thoughts on warranty snooping was that there are far more legitimate and non-modded vehicles that go in for warranty work than modded vehicles (I would think). What's the percentage, I'm sure there's some numbers somewhere, based on the type of vehicle, or those that are modded in a way that could void warranty. But then there is the "use" side, too; I overheard a claim at a local dealership about a vert body issue being denied warranty coverage because the car had been "racing. This was years ago before any mods or thoughts of mods were on my mind, but it just was something I remembered.
If an insurance rep is writing down vin numbers at a track, I think that's bullshit. It's your business what you do with your property, and how you wish to operate it within risky situations.
Being a strong privacy advocate, there surely will be a time when it will come up, as to what information can be obtained from your vehicle, for whatever devious reasons are claimed. Sure there's the 'we want to validate your operation to provide the best insurance rates' bullshit story, but think about it from a bigger picture as mentioned. Knowing how and what you do to your car. Where you drive, how fast, how close to other vehicles, and then the remote command and control, where law enforcement says "we need to stop this vehicle, so remotely disable it" kinds of things. That's when big brother is already too deep. Once it's been there and it is in place, there's no going back.
The recent rage of muscle car resurgence may be an era we were fortunate to have lived and played in. 10 or 20 years from now, when more and more cars are less powerful or non-modified, and even driving themselves, these days of "before the motor law" will be missed.
sorry for the divergence.
