After being mentioned as a possibility before the start of the 2012 season by Beuax Barfield, starting at Long Beach this week, pit road will only close during full-course caution periods if it is an emergency on road and street circuits. Hopefully, this will decrease the rush of a full field of cars on to the pit lane at once and decrease the amount of danger the pit crew members face during pit stops. Barfield has not mentioned leaving the pits open for oval races as well.
Also, announced today, starting officially this weekend lapped cars will move to the rear of the field on a restart in the final 20 laps on a road or street circuit.
