Unpopular opinion from someone not from Orange County

Why are people so rude here? I grew up in San Diego and went to college in Northern California and now I live in south Orange County for context.

I commute to Irvine a couple times a week (I work from home most days) I get cut off EVERY time I drive to work, no one holds open the door for anyone everywhere I go, no one says thank you, no one looks at each other and says hi. It feels like a very selfish disconnected community and I’m curious if I’m the only one that feels this way.

I love the beautiful town I live in but it’s hard to love the people that come with it. I understand the hustle and bustle but when did being a good person get left behind? Has it always been this way?
