Motorway Mate

Also knows as a "Freeway Friend" (United States, Canada, Australia, South Africa) is a term used to describe a motorist directly in front/behind you who is on a similarly long journey on the same motorway/freeway, especially at night and when driving alone. Though you have never and are never likely to meet the person driving, you form a bond with them and can take comfort in the fact that you're not the only one driving hundreds of miles. Becoming more common now with the invent of Adaptive Cruise Control.
