During the morning rush hour, queues can tail back onto the motorway from the city centre. In 2014, the Highways Agency reported that the M32 between junctions 1 and 2 was the most unreliable motorway journey along the entire M4 corridor between London and South Wales, with over 56 per cent of journeys taking longer than predicted.

M4 carbine Marine Corps Infantry Automatic Rifle testing, the Colt IAR displayed a MRBS of CLASS I/II Stoppages of 952 rounds, with a MRBEFF of Class III Stoppages of 60,000 rounds. An array of firearms accessory makers have offered gas piston conversion kits for the M4. The claimed benefits include less needed lubrication for the bolt carrier group to run reliably and reduced fouling. The argument against it is increased weight and reduced accuracy. The Enhanced M4 uses an articulating link piston operating system. Complicating the Army search for higher reliability in the M4 is a number of observations of M4 gas
