Lewis Hamilton sets fastest time of second practice at the Korean International Circuit. Nico Rosberg crashes.
Rain began to fall again in Korea just in time for the start of the second session. First practice was run in the wet, but the rain eased off during FP2, and many drivers decided to risk going onto slicks towards the end of the session. "I can't get any heat in the tyres," Button complained over the pit radio and returned to the pits after posting only one lap on slicks.
