I think we're reading void in different ways. My understanding is that if you are chugging along towards Mid-Ohio with warranty protection and, say, your steering were to suddenly come loose, you're covered. However, if what you do on that track once you get there causes the steering to come loose, you're screwed if it happens on-track. If you are driving home from the track and your steering comes loose, you're covered because it happened on the road, but the burden is on the company to prove that negligent use on-track caused the fault. If they're successful in that, you're screwed.
In my view of the Raptor issues, their issues arose due to abusive usage off-road (description of absive usage is subjective and to be decided by the courts I guess). Regardless of the way the truck is marketed, I highly doubt that these issues would've come to light in the course of daily driving within the speed parameters of the law. That burden will be on the consumers, apparently, to prove.
