When I was visiting (5 years ago):
- The trains didn't work
- People printed out google maps instructions instead of using a network connection because data connections were bad/expensive
- I had to sign my name to pay with a card at gas stations. I couldn't use an electronic payment card, only credit cards worked.
Now these are just examples off the top of my head. In my home country of Finland, the trains work, internet and utilities work (we don't have blackouts), payment is usually done by NFC for small amounts, card readers (with pin) for larger amounts.
If you're talking about industrial technology, I don't have enough information to compare. But I would assume Europe has better manufacturing. After all, Germany makes all the cars that end up in the US.
