Research from Tempcover found more than one in 10 Gen Z drivers missed out on a dream job interview because they were too anxious to drive.
10% turned down promotions that needed more time on the road.
Only 32% of Gen Z felt confident driving alone for journeys of three hours or more.
Jake Lambert, temporary car insurance expert at Tempcover, said: “The research exposes a hidden crisis on our roads where a generation of drivers, despite being legally qualified, are finding the reality of driving so overwhelming that it is potentially life limiting.
“When motorists are turning down promotions or missing interviews because they are too anxious to drive to the location, this ceases to be just a motoring issue and becomes a broader societal one.
“Confidence comes with experience, but if drivers are avoiding the road, they never bridge that gap.”
