inside travel - USA vs Europe

In USA, generally, traveling interstates is generally the same experience - for the most part, the road signs, the kind of shops, restaurants, language , currency are similar, so you would not know much difference in another state, and with a car just navigate with one GPS.

How is this in Europe - is there lot of country hoping for vacation, shopping like how someone may quickly go from North Texas to OK or NJ to NY etc. Is the experience very varying or difficult to adjust in a near by country. Are most European country bilingual (English & French etc)?

any other similarity/difference between USA and Europe in this regard, from your experience?

Those from Europe, have you found adjusting to a USA travel easy and no issue?if there an issue, what was it? and vice versa...

thanks
