Top Gear may be getting viewers’ thumbs up when it comes to watching the show, but one of its hosts, Jeremy Clarkson, got a thumbs down when it came to choosing a celebrity co-driver for a 4×4 adventure, according to new research by Continental Tyres.

The outspoken TV presenter was rated as the worst person to share a 4×4 drive across the Sahara Desert in the poll of 2,000 motorists. Clarkson was followed closely by media persona and former model Katie Price and Prime Minister David Cameron who finished third.

“Jeremy Clarkson might have motoring credentials but either his calamitous road trips on Top Gear his lack of practical skills or his outspoken views mean most people would leave him behind,” said Tim Bailey, spokesperson for Continental Tyres.

On the other side of the spectrum, when men were asked which female celebrity they would select for the journey, Playboy model Kelly Brook was number one, while women chose Twilight star Robert Pattinson.

According to the poll, some 75 percent of drivers would ditch a celebrity altogether and nearly half would prefer to have a family member sitting on the passenger side.
