Uninterested in doing it by car maybe, but not uninterested. Just that we have good(ish) train, plane, ferry and coach services - most people I know (I'm British) will have traveled a lot in Europe.

Also, don't forget that doing it by car is pricey for us - another comment above quoted $2.50 or something a gallon in parts of the US - here we pay about £1.20 a litre currently - so for example the cost to my brother of driving his van from the UK to northern Portugal (which he does to take his tools with him) can cost about £360 - where as he could fly and then hire a car there for a week or two for less money (if having his tools to do up his house there wasn't the reason for visiting!)
