The number of single-vehicle rollover accidents in my area is astounding.
A typical example is the yahoo doing 110mph in a 75mph zone, then not noticing a clump of traffic in front of him moving at "only" 85mph. Brake, swerve, lose control, roll.
Then somehow he gets behind the wheel of another 110mph+ vehicle and does it all again.
And not a lesson was learned that day, or ever.
