I am confused by your post. Are we talking baby car seats? Your seat? Your wife's seat? What exactly is happening? Also, you have slid the backseat back as far as it goes already?
Not to mention the people who dont want to leave their entire life decisions up to software code "written" by some dude letting AI fire up a PR he spends 15 seconds scanning while the WOW server is loading.
Testing videos are great.
Unless you are blind you can look at 5k mile oil and 10k mile oil and see the difference. If you do that and still believe Toyota's 10k change then I guess good luck.
If you are worried about warranty and money isnt an issue just stick with toyota parts installed at the dealer. TRD lift, TRD Pro wheels, and stick with the same Falken Wildpeaks but maybe air them down slightly. Done. Easy.
