I don’t think either had an EV option suiting my needs when we bought a Model X? Meaning able to seat 6-7 humans and ~300 miles of range in the battery pack?
Do they even have a viable option today? (I’m unaware how the Lexus electrification is going.)
Forget Toyota/Lexus, that's a bit of a red herring - the point is that there was literally no competition for Tesla in three-row electric vehicles when you bought yours.
Now, you have the choice of a Mercedes-Benz EQB or EQS, a Rivian R1S (as you chose) or a Kia EV9 with Lucid, Hyundai and VW all with products about to enter the market.
