Seems like this could be resolved easily by creating a ground which drags from the bottom of the cars which discharges the electricity, but I'm no engineer.
The problem is that an earthing strap under the car, would it be in constant contact and at the same time being eroded, with the added problem of bits coming off it. The other posibility is a deployable strap at slower speeds, say in conjunction with second gear to earth the car. This brings up the question of what happen if it fails........pit stop and 18 mechanics all doing the dying fly(

)
Another problem with with any static charge, how do we earth the driver without giving him a zap? It is reported that there may be "special boots" for the drivers in development, so that when they touch the ground, they are earthed. Great, so they get out of the car insulated, a walking capacitor and they then zap the first person to shake hands with them.........I have won am everyone is running away from me

Maybe Williams are not so wrong after all :-?

1. Captain, if the problem is not entered into the technical logbook.........then the aircraft does not have a problem.
2. And, if you have time to write the fault on a napkin and attach to it to the yoke.........you have time to write it in the tech log....see point 1.
