shorter stopping distances, less skidding.
When I worked at Shell material was known as SHELLGRIP. Expensive, so use restricted
to junction approaches where stopping distances critical. However, Shell sold off their
COLAS road surfacing businesses to some French outfit.
However, I don't see real benefits using on an open stretch as it were.
As others say, real issue is
traffic density is far above what was originally envisaged.
Being so overcapacity any disruption to flow quickly clogs up local road network.
