Not me as i'm guessing the video not having any sound means it's REALLY, REALLY LOUD!!!!

there again, shooting all the refuse at passers by as you fly down the street cancels that one out.

I would have 12 points within 3 minutes of driving one of those though

I passed only last year if I get 6 points I loose my license.
Driving a hundred miles a day presents plenty of point gathering opportunities too.

Try not to drive like a nob, and follow instructions given on roadside signs.

but the video makes me less so. Unless they can get it out of ground effect its nothing more than a hovercraft.

but does this not work on different principles? i.e. it lacks a "skirt" (or trousers for that matter)

the difference here is that there's no skirt trapping that air, therefore it requires much greater power to achieve the same result.

just serves to contain and thus increase the air pressure below the vehicle, but the same effect can be achieved without one.
However, the vehicle above isn't using ground effect -- that requires a wing or other aerodynamic surface in order to be generated.

That Lun-class one reawakens my inner 10 year old...the one that used to get books about military aircraft out from the library every fortnight.

I can assure you that they most certainly do experience ground effect, and therefore so will this.
And what's a rotor blade if not a wing or other aerodynamic surface? It is best thought of as a wing that is being forced through the air by an engine rather than by the forward motion of the vehicle.

creating lift from the pressure differential between the top and bottom of the blades as they move through the air. They do indeed experience the ground effect, where the pressure below the blade is increased due to proximity to the ground.
Hovercraft and the vehicle in the OP work on a different principle, using fans to create a cushion of high pressure air below the vehicle. The ground effect plays little to no part in that situation.

Your first point agrees with what I said, and your second flat contradicts your first.
The fans are nothing more than ducted rotors - the duct improving the efficiency of the rotors. Ground effect is nothing more than a high-pressure zone of air caused by proximity to the ground - as you yourself said. It is clearly important for hovercraft and as evidence for this, ask yourself why hovercraft can't fly like helicopters.
As to my original point, right at the top of this thread - this vehicle is clearly operating in ground effect. Until they can make it operate out of ground effect they've achieved nothing novel other than a hovercraft with excessive power requirements.

and hence the ground effect doesn't come into effect.
I'm off to Solfest now, so can't elaborate further...

a car is faster, quieter, and less energy intensive.
