Downforce flaps that open when you are driving on walls or the ceiling

Something that has always bothered me is the fact that the cars seem to generate downforce to drive on walls and ceilings at will.

Obviously in real life cars are designed to generate downforce in a single direction, down, however grip cars can drive upside down too, and since they look the same either way up, downforce is not generated by the bodywork.

Having a few flaps and fins that open on the car when you drive on walls or ceilings would be such a nice detail to see.

I would like to see the car react to surroundings and events too, but if it is going to be added it will probably be done towards the end of development.

You know... this is actually a really good point because to create downforce normally, you would need a differing shape from one side to the other... which as you pointed out is not actually a thing in these vehicles.

For whatever reason, I always thought that to achieve downforce from these cars, that whichever side it was on, the front of the car would always drop lower then the back, and thus, creating a low pressure zone under the car like a diffuser.

However, active aerodynamics like on the Pagani Huayra would be an excellent addition and make these vehicles much more believable.

You could actually suck the car to the ground using a vacuum while maintaining a symmetrical shape.

While this is true, the fan required to actually create a vacuum underneath the car would be enormous and run at some serious speed since the volume of air that would need to be moved would be so immense due to the lack of ground effects and the fact that there is such a large gap under each car to the surface. However, the force generated by such a fan would probably be more than sufficient to hold the car upside down even at a complete stand still.

That idea however did give me another idea. What about a 'ram air' downforce system? Air is taken in at the front of the vehicle (plenty of space to do it seeing as most of these vehicles have completely blunt front ends) and 'redirected', depending on which side is up, to vents on the top of the vehicle... preferably one near each wheel or one in line with each axle. At the speeds these things travel, it seems rather easy to imagine them having the capability of redirecting enough air in this way to actually create some useful downforce.

These things weigh a few tons. If you want their appearance to match their capabilities, we'd have to slap wings and a tailplane on them.
It would work well with the turbine engines on the back, sure, but then we're gonna have to take a look at other things as well.

EMP permanently disables your own car and doesn't display any visual feedback.
The blue barrier keeping you inside the racing tracks has to be removed.
The system that keeps angular velocity on collision in check has to be removed, 'cause real cars tumble like crazy when they hit something.
80% of development resources go towards terrain deformation, 'cause stuff warps when you hit it with say... 648 megajoules (jebus... and that's with the cars weighing a understated 90.000 kg).

I get it, immersion requires illusion and maybe the current car models just don't cut it for you, but when in doubt (excuse me for linking to this trash):
