An F1 car generates down-force equal to it’s weight at 150km/hr. Theoretically once down-force exceeds weight a car can drive upside down. Today I am reading automotive aerodynamics and I am wondering if we’ll ever see double roads where cars can drive on top and on the underside.

We’d need an interchange of sorts to facilitate the lower speed position from the higher speed position. More challenging will be the stopping…
Sure starting and stopping must be on a normal position.

Once saw a clip on telly of a road round a sharp bend that is almost vertical. I will be happy to see that clip again.
you can imagine how breathtaking it would be driving 200 km/hr upside down with an entire city below you.

How is the downforce generated? By acting against the atmospheric pressure? Cos if that’s the case, the theory isn’t valid.
some things are said to be possible but have no practical application in the real world. next…
That’s not down force… Downforce is generated by the speed of an object subject to its weight and aerodynamics I.e. How the wind is reacting to the object speed. Down force is the force that pushes a car down the tarmac.
I think he means that when you start slowing down, gari itaanguka.
The same way an aircraft aerofoil generates lift but now inverted.
We cannot really rely on down-force alone. Assumption being that the need to stop or slow down will definately happen. Therefore the best way to go about this wld to establish electromagnetic rails to literally suspend the vehicle in the air or if we are really thinking this way develop teleportation devices and cut transport cost completely…
Coyote used to face the same conundrum when he’d chase Road Runner up a cliff then stop at the precipice upside down. Sadly, only the Coyote used to fall down.
Alot of theories had no practical use when first discovered
Weight (gravity) or there’s another force?
leo niaje uko slow hivi, think an aeroplane vile umeambiwa, the shape of the wing create uplift when it reaches a certain speed. Now invert that wing, the force is nolonger uplift but down force, comprende?
Hapa labda train, its tracks will guide it will speeding up or slowly down to come back to normal position. But the seats also have to be able to rotate counter to the position of the train coz, people pass out when they are upside down for too long

Leo @aviator anastaajabisha!
Am thinking of a Nissan matatu. Its shape is nowhere near a plane’s wing. What keeps it on the tarmac kama sio weight?
think along the lines of a fomula 1 one car, two different aerodynamic profiles, one has inverted wings the other doesn’t. This down force improves their ability to corner at high speeds
Woi ngai jesu… A mat is not aerodynamic enough to create any down force… Look at exotic cars, supercars and cars built for speed, and I emphasis the last bit built for speed.
