This is also true... so... how do we overcome this problem? Well... we have some Giant Jet Engines and tons of thrust at our disposal... we can remedy the wheel spin (from just taming it to completely eliminating it altogether).
If on the tops of the cars (either side... doesn't really matter as long as the force is going the correct direction) we had directed exhaust vents, we could effectively eliminate wheel spin off the line and increase traction. This would basically work like the fan car that was banned from formula one but rather than creating a vacuum below the car, we create a high pressure region above the car instead. Instant downforce from a standstill.
Believable, Doable, Quick Acceleration, No wheel spin (depending on the surface and the amount of force directed to being perpendicular to the car). This could also gradually cut out above about 200 to 300 as the car would then be generating enough downforce to solve these problems for itself
