Who said anything about ice? Not me, the comparison by Julian was that lifting a bit of the car was like driving on ice. A car that generates no lift, as was proposed when the brakes are applied, has no difference to an ordinary car, other than the benefit of air brakes. I cannot see how that is in any way worse.
"Lots of just plain wrong data in this post mostly about how aircraft fly." Please let me know what is wrong.
Ground effect vehicles are very different to planes.
Edit:
To make things clear for everyone picking up on issues already addressed.
- lift is only employed when steering angle is very small
- lift is only employed when brakes aren't applied
- lift can be cancelled out at any point
- The car is never fully off the ground
- Ride height controls the amount of lift
- Lift is only employed in a straight line at cruise
- The wheels still drive the car, because they never leave the ground
Going round corners is unaffected, because of steering angle sensors that cut lift. Braking is unaffected because of airbrakes and brake sensors that cut lift. All of these are already addressed.
The debate is about cruise.
