This is due to the fact that water does not pool on the surface of PFC layers. Since less light can be reflected from oncoming vehicles, pavement markings are more visible.

Benefits related to safety include reduced potential for hydroplaning, improved wet weather frictional properties, reduced wet weather accidents, reduced splash and spray, reduced glare, and improved vision in seeing pavement markings. Benefits related to driving comfort include smooth wearing layers (and, thus, improved fuel economy)
