Mary McCarthy has been driving for almost 20 years, but has only driven on the motorway about ten times in her life because they terrify her.
"I can remember every time I used one, and it was an absolute disaster."
"I sit in my lane and I'm frozen, totally petrified. I can't overtake and because you don't overtake, people start to beep at you and that drives me into more of a frenzy," she says.
Over time, her fear built up, and she just began to avoid motorway driving altogether.
Mary says for her driving on the motorway is akin to playing the video game Mario Kart, with the speed of other drivers making her anxious.
