Failure to either test for or to detect trailing-throttle oversteer is a
pretty simplistic screw-up. Particularly when testing a flagship $55K
family SUV.

Suspension changes should have corrected this before a failed attempt to
cover it up with electronics.

This gent told Congress that he grew up in the company as a test driver.
