For the 2013 Korean Grand Prix the pit exit was extended out around turn 1 to rejoin the circuit at the end of turn 2, as was on the original plans for the track. The quality of the work has been called into question by many drivers, with many highlighting an uneven surface as being "not the standard that it should be". This is due to the pit lane being extended through the run off area, which has a drainage system running through it.
