As an American the thought of multiple other countries being within driving distance is completely foreign and bizarre to me. I have to drive 3 hours to see family and I don't even leave the state.
China (larger than the US but smaller than Canada) has 16 tripoints and Russia (larger than the US and Canada) has at least 11 tripoints:

edit: I misread the list of countries by area on Wikipedia - US is slightly larger than China....

Then continuing the journey around Europe, there were even more currencies and more languages and different cuisines.
Ah the nostalgia!
