You just have classic FOMO and with Teslas, you have to override your monkey brain to stop wanting the latest and greatest. When I was younger in my 20s, my brain compelled me to buy the newest Android. I loved having the new tech and I always thought I could sell my old phones before they became obsolete.

Teslas feel very similar to that high you get from having the latest phone. I own a 2017 model S and it seems every 6 months my car becomes more legacy.

First it was all the packages (Cold weather, premium upgrades, etc) becoming standard when you had to pay for the packages.

Then it was HW 3.0 & MCU 2 for advanced screen graphics and playing Netflix. Also capability for Full Self driving.

Then it was the raven air suspension.

Then it was model 3 and model Ys getting external pedestrian speakers that could play music.

Then it was a heat pump.

Then it was being to roll your windows up and down through the phone app.

Then it was faster super charging.

Then it was new, fun video games.

Then it was a rectangular screen that can play witcher and tilt (eventually)

Then it was more battery range.

...and so on.

That's all I could list off my memory but I bet you I missed 50% of the updates. The moment you buy a Tesla, it'll be out of date in a couple of months. It is what it is.
