Along with drag, anyone that drives on the highways and freeways should also be concerned about aerodynamic lift.
When air pressure builds up and generates lift, it reduces your tires' available traction, since it is taking the weight off of the road, but inertia still applies. This leads to longer braking distances, less control when swerving to avoid an accident, and the possibility of spinning out of control.
Since to
some people it seems to be completely foreign, I thought they would like to know it's common knowledge to those in the real world:

"The Corvair was found to wander excessively at highway speeds, dangerous nose lift was a real concern and for this reason aerodynamic studies were performed inside engineering."
"The front valance and rear deck spoiler were more than mere styling gimmicks. They actually made a measurable contribution to cornering and stability at highway speeds"
Over time, I'll be collecting data and articles related to the negative aspects of lift.
