The modern Toyotas have an advanced cooling system with computer-controlled valves that direct coolant to high-wear areas during warmup. In cold weather, ours starts up and does not enter EV mode at all for several minutes. It's not hard to computer-control these sorts of things in 2024.It is biased to lower fuel consumption, not to minimize wear. If it is meant to do that it would need to led the ICE run under load for quite while until oil temps get real up. Our daughters Honda Accord Hybrid definitely does not do that, I am sure Toyota is trying to please EPA goals and MPG marketing as well.
I don't disagree that CAFE standards lead to rube goldberg systems like this, BUT Toyota has certainly thought of the wear issue and addressed it. Their hybrids have been out for 20 years at this point and are very reliable (outside of EGR problems in one of the previous Prius gens). I'd avoid knocking Toyota hybrid until you've owned one. They are exceptional.
I'll snap some pictures when I remember underhood of our Highlander Hybrid and my GX470. Spoiler alert: The GX470 is significantly more complicated, packed, and harder to work on. There is room for a whole family of racoons under the hood of the Highlander, despite it being 16 years newer. The header install on my GX took a whopping ~20 hours of my time.
