I doubt people are being thought to sit on the footbrake if they are they are being thought to drive against the highway code.I'd forgotten that, headlights aren't required on lit streets? Surely that needs to be updated? With the invention of DRL we now have the scenario lights on at all times, which makes this rule a bit of an odd one.
People sitting on footbrakes are often driving autos. Apparently it's better for the gearbox to keep it in drive and stay on the footbrake. I've also been told that new drivers are told to use footbrakes because the brakes are then applied to 4 wheels instead of 2.
"In stationary queues of traffic, drivers should apply the parking brake and, once the following traffic has stopped, take their foot off the footbrake to deactivate the vehicle brake lights. This will minimise glare to road users behind until the traffic moves again."
DRL aren't headlights though, it's specifically headlights you still need your sidelights on.
I think this also applies.
"You MUST NOT
use any lights in a way which would dazzle or cause discomfort to other road users, including pedestrians, cyclists and horse riders"
