What do you like to observe when traveling?

When solo traveling, I have more time and attention to take in the place more. What are some things you like to observe or compare when you’re in a new city?

Some things for me are:
-taking public transportation and comparing the experience, ease, cost to what I’m use to at home
-how many people are walking around the streets. Is it empty and everyone takes a car? Or do a lot of people walk around with families and friends?
-cafes. Are people there working/on their laptops, or are people there with friends and socializing.

I find actively observing these things help me understand the culture more. What are some things you guys like to take note of when going to a new place?
