Webber backs new DRS restrictions

Mark Webber has welcomed the adjustment to DRS regulations for the 2013 Formula 1 season, saying drivers had long felt the system's free use in practice was pointless. Until this year, the straightline speed-boosting device could be utilised freely in practice or qualifying before being restricted to its designated zones in the race. This meant teams had to optimise their set-ups around its ample use in qualifying even though this was not possible on Sundays
