The edge between manufacturers in any given measurable attribute of vehicle performance is far, far smaller than a bunch of screeching fanboys on the internet would have you believe. If it weren't you'd see far less diversity of vehicles on the road.
The humvee is also used by militaries all around the world. It's not known for particularly great reliability. Militaries have a much difference set of objectives when it comes to labor vs supply chain complexity vs cost than civilian entities and individuals do.
Poor countries in Africa and the middle east use Toyotas a lot for the same reason they still use 7.62 intermediate cartridges a lot. It's what they have, it's what their supply chains are tuned for. It does the job they need, not necessarily with maximal efficiency but well enough they can't justify the cost of switching.
Meanwhile in the civilian market Toyotas cost more, don't do good incentives/rebates and financing is more limited. This drives people on a budget to other brands. This means Toyotas wind up in the hands of people who treat them proportionally nicer. A Tacoma rolls off the lot and into an upscale garage. A Colorado rolls off the dealer lot and into a commercial fleet where it will be driven by a bunch of people who aren't paid enough to care. A Camry will have one ass in one seat for the first 100k and it will go from home to work and home to work. An Altima will spend its first 100k dragging a family of four all of the places they need to go. A Sienna's first owner will go to home Depot, buy 3000lb of pavers and rent the truck to drive it home. A Town and Country's first owner will put that in the van without thinking twice.
See what I'm getting at here? Being expensive up front means that only people who can afford to be nice to things get their hands on them, at least initially, that means the vehicles rack up more miles and years before they see hard use. Any vehicle not fundamentally flawed to begin with can look reliable in the hands of these people. I can present other examples of this if Toyota is too emotional of a topic for people to discuss.
Also it should go without saying that we're talking in broad generalizations here.
I do agree with you that the scale difference between Tesla and Toyota is massive and comparison between them is silly.
