Let’s say you had the chance to drive a Hummer over 1,000 miles across the Sahara Desert. As part of an organized group, you wouldn’t need to worry about things like food and water, spare parts or even emergency supplies; in fact, all you’d have to do is pick your co-driver, and name the celebrity co-driver you’d least enjoy spending time with.

That was the question posed to 2,000 motorists by Continental Tires, which is sponsoring the Conti 4x4 Trophy for residents of the U.K and Ireland. Winners will get to cross both mountains and deserts as part of a guided expedition; while no off-roading experience is necessary, the trip will still have its potential dangers.

As Continental Tire spokesman Tim Bailey explains, “Driving thousands of miles through  the Atlas Mountains and the fiery sands of the Sahara Desert makes your choice of co-driver incredibly important.”

Three quarters of those responding wouldn’t want to make the trip with a celebrity, with half of this group opting for friends and the other half family. Among male respondents, Kelly Brook was the most chosen co-driver, while among female respondents Robert Pattinson most often got the nod as navigator.

Which British celebrities would drivers least favor? Topping the list, to no one’s surprise, is Top Gear’s Jeremy Clarkson. Sure, Jezza is entertaining to watch on television, but exotic road trips on Top Gear often end in disaster. Also, Clarkson isn’t exactly known for his easy-going, laid-back attitude.

Next on the list was Katie Price, also known as Jordan, a topless-model-turned-reality-TV-star-turned-singer-turned-businesswoman. Price was followed by British Prime Minister David Cameron, who was trailed by rail-thin model Kate Moss.

Other notable celebrities making the list included Madonna, Simon Cowell and Lewis Hamilton, and we certainly understand why on all three counts. We’d probably enjoy talking to Hamilton (briefly, at least), but we’re betting the F1 star would have a hard time giving up the driver’s seat.
