They kind of already did that. They all bought used cars, and took them to a forensics lab to have the interiors inspected. Hammond's had nose pickings in it, and Jeremy's had cocaine and "sex juice" in his. And yes, the show was a riot.
Oh gosh that’s right! :D
And it WAS better entertainment than most anything else on TV!
My grandkids watched a few episodes with me a few weeks ago. The Robin Rocket; Caravaning; something else... They laughed and liked it a lot.
I think their Road Trip specials will be great geopolitical teaching tools.
