The issue is that the alternatives generally aren’t that much better in a vacuum. Infotainment vs Tesla infotainment (removing the CarPlay merits): It’s not even close. Tesla is like 10-15 years ahead of everything else on the US market in their price range. Car manufacturers famously lock in their tech and designs something like 3 years before public release.
Will there be meaningful software updates for your Kia EV6 in 2028? Absolutely not, no way.
Do you want to tow anything more than 1000Kg? Good luck outside of Tesla.
NACS? Not one single other car available yet.
Do you want a dashcam? Rivian is the only other brand, IIRC.
I’m not apologizing for Tesla, but it’s really painful how awful all other cars are compared to the competition.
Issue with waiting for the R2/3 is that the tax credits will probably be gone by then.
