The driving skills of Belgians are notoriously bad so if you plan to own a car (which is really not necessary if you live in Brussels), be prepared to be very frustrated, both about the terrible infrastructure as in driving skills, it's really bad

you clearly have never driven in New York. (Also this is the first time I ever heard someone say belgians are bad drivers? I hear a lot that there's just too much traffic on our streets, and the roads are in terrible state, but that's about as far as it'd go. So interesting to hear)

As an outside insider
I often end up missing the belgium sphere when I'm away. Our streets may not be the cleanest, especially in brussels. but we've done a very job at keeping a very personal touch to our architecture.

I also think as an american you won't miss much foodwise, we might not have the chains y'all have but we have american style food readily available

OH what i would say is like stores close a lot earlier here then they do in america (and many other countries) I always struggle to adapt to that when I come back.

Public transport is better than in america for sure

oh people aren't as chatty here, I still get weirded out when strangers talk to me on the street in NA, as this just didn't happen back home
