This was mentioned by 1973/126 et al at the weekend and has been a background thought since then... It is probably the craziest thing I've ever considered... but I'm considering it!
Ideally, I'd like to bring my son (if anything, just to show him he'll never out-crazy his Mum when he's older!), but not sure this is a good idea for a nine year old? Anyone else considering taking along a small person?? We survived a camping/driving holiday for seven days last year...!

Personally, I think it would be a great thing for him to experience.
Otherwise, a suggestion: what about using walkie-talkie radios for the drive - to maybe shout out a petrol need or problem or whatever? That'd be just like Top Gear...

Anyway, definitely interested!
