Moved here from the northeast and this culture shock is real

Three months in. Some observations from someone still adjusting.

• Everyone drives everywhere. I asked a coworker if they wanted to walk to the restaurant across the street. They looked at me like I suggested walking to the moon.
• People genuinely say "sir" and "ma'am" and it's not sarcastic
• The speed limit says 65 but everyone is doing 80 and if you go 70 you're in the way
• Restaurants bring chips and salsa like it's bread and butter. I am not complaining.
• There is no public transit. I mean there technically is, but no.
• People talk to you at the grocery store. Like full conversations. Strangers.

Not saying any of this is bad. Just very different. What else should I brace for?
