I have an invention, i shall call REVDIS (Repetitive Exterior Visual Directional Intention System)

Are you going to fit your prototype to the i3 or the 335d?

I invented the phoneless cord.

A powerful air jet directed downwards would provide additional lift at precisely the moment you don't want it...

Well, you are right. My friend performed a calculation for me - the air stream should impose a force of about 645 N per a wheel if the car is driving at 20 m/s (=72 km/h) through a 1 cm deep water. This times four wheels gives the force 2580 N what is about 1/4 of the car weigth. But I think the upward jet force of this value reduces the friction by a less percent than the aquaplanning.
