But your general assertion that modern cars suffer increased final oversteer as the speeds increase is simply false. You are mistaken.
It would be a disservice to the readers of these forums to allow this to go unchallenged.
I ask you to produce authoritative proof of your assertion on a broad, general scale.

Hey look my vehicle dynamics textbook is online!
Vehicle Stability
Basically in the section linked Figure 6.11 illustrates that a car setup for oversteer (like the FRS) will likely be more unstable at high speeds and a vehicle set up for undeersteer is stable at higher speeds. It's why 911's are so successful in racing but have a reputation for being hard to control for everyone else. It also explicitly states in the paragraph below the figure that a car that understeers will understeer MORE at higher speeds when comparing similar steering inputs (the graph shows the understeer line dropping off, representing unresponsiveness).
This is simplified and doesn't delve into specifics but I think it shows nicely that depending on the setup, some cars are stable, some aren't, depends on the car. And like you explained, not many people are willing to test this, much less journalists borrowing cars.
Don't you just love it when everybody is right?
