I find the Tesla seat material causes my back to sweat much more than previous vehicles with leather or cloth seats so ventilated seats for me is possibly the most wanted change out of all the things coming in 2022 so far. The CPU upgrade will make next to no different now in the way the vehicle/navigation works (outside of games maybe), but there could come a time where some features are only available on the newer CPU so it does make sense to hold out for that if you can afford to wait.The ventilated seats are tempting prospect, but the friend of mine with super bad flatulence lives a long way away and seldom see him these days! Just have to open the window instead of having seat ventilation!
The laminated front glass made little to no difference in interior sound tests people have conducted, so I cannot see the rears doing anything either. No one is really sure why Tesla has added it - was it for sound insulation, heat insulation, security or safety? From a noise point of view there are other areas to tackle that would make more of a difference than side glass. Certainly worth having if it comes with it but I don't think this one is worth delaying a delivery for.
