Here in Spain I noticed everyone drives so fast, too dangerously fast even in a school or residential neighborhood where there are many pedestrians. But I don't understand exactly why?
It really depends.if it's offensive, then yes. Most likely they noticed it but didn't care
Some I packed a lot and used like.. half of what I brought. You can also do a web search on this topic, that is what I did a lot of sites have a suggested checklist. I hope my answer helped you. Good luck and congrats.
