Lewis Hamilton set the fastest time in a soaking wet final practice session for the U.S. Grand Prix, which could end up setting Sunday's grid if qualifying is rained off.
Formula One's rules state that the final practice standings will be used to decide the grid if qualifying cannot take place ahead of the race, which added extra importance to the morning's session. All the drivers headed out on track in search of a quick time, with the FIA enforcing the use of full wet tyres in the treacherous conditions. Fans, however, were told to stay at home until midday, meaning the session -- which was busy even by the standards of a dry final practice -- unfolded in front of empty grandstands.
