flying cars and flying boats

[gttouring]

in regards to flying cars, blamed on too much power and speed, I recently saw the F1Boat Racers and the boats (in the hightlight real) take to the air much more often than indy cars, the instance is the same however, a small amount of air gets under the boat and its travelling surface, and it lifts up and over, and as it come crashing down the airbag allover the boat open up to help it stay afloat you get the idea.
What so these boats travelling much slower, and IRL cars have in common- if any thing? and what about the aerodynamic issues in common, they certainly are not flat bottomed but twin keel with a center portion, in essence 3 ski type shapes and twin tunnels (so is that 3 keels?)

and if the car gets to an angle of greater than X degrees why not have a side pod wing deploy to bring it down? or an airbrake? the gyroscope needed to read such an angle is relatively cheap and if it can be used to keep a Segway HT scooter upright than I am sure the design can be adpated to indy cars to keep them horizontal instead of veritical or inverted.
