I very much doubt that NHTSA and USDOT would allow in-car ads. The consumer backlash to that as a stock "feature" would be extreme - I know I would immediately scratch any car with that off my list of possible purchases regardless of any other features, costs, or performance figures.
In unrelated random thoughts - I'm severely disappointed in how many 4WD vehicles you can really modify for off road driving. After the Moab Meet and the Xterra's second mid-trip breakdown in a row, I'm realizing that I need a newer and more reliable vehicle. The problem is I want to go a different direction; I'm done with the overland thing and want to focus more on technical off road challenges. Part of that is because all the overlanding I've done, I could do with a more hardcore off road build by throwing a water jug in the back, the other part is the Broverlander Instagram thing has really soured me on the whole idea. I'm sick of seeing Tacomas with $10-20k worth of shit bolted on driving their commute every day with maxtrax, a roof top tent, and a half dozen rotopax strapped to the sides.
I'm realizing that if I want to go up in tire size - which I do, the X really struggled on 33" tires on some trails - there's almost no options out there aside from Jeep. The Wrangler Unlimited is crazy expensive for what you get, but a 4Runner TRD Pro can be as much as $10K more than that. I'm not sure I want to buy into a FCA "American Leyland" product, but I might not have much choice. The only other modern vehicle I know of that can run 35"s is the new Bronco, but it's not out yet and Ford is having serious issues with that 10-speed. All the lego-bits that I want are there, but Ford won't bolt them together the way I want: V6, Manual Transmission, Sasquatch Package. I can get the Manual and the Sasquatch, but only with the 4-cyl and I honestly am not confident that little high-strung engine will last running desert trails at < 5 mph without cooking the turbo.
