If you look closely at your first source, you’ll notice it’s specific to Australia, and assumes Australian prices for gas and electricity, as well a hugely different depreciation for the two cars.
Doing the same math for most American states will punish the Tesla.
US prices for fuel are lower, but so is the cost of electricity in the US. It’s about half the cost per mile to drive an EV vs a light combustion vehicle.
Why is a 5 year cost of ownership relevant when a Toyota has a proven track record of lasting 10 to 20+ years and 200k to 300k+ miles without needing anything other than cheap routine care?
Surely the evidence is stronger for cost per mile and cost per year being lower for a Toyota than a Tesla over the whole lifetime of the vehicle.
Most people own a car no longer than 10-12 years. If governments are phasing out combustion vehicle sales, I don’t see how 20+ year longevity is relevant when the infrastructure to support such a vehicle might not even exist at that point. Gas stations will wind down at some point as consumption tipping points are reached. Bosch in Germany is already preparing to close some facilities that produce ICE specific components.
Why does it matter if they own it or not? They still get the value from a functional vehicle if/when they sell it since the buyer will pay more for it.
It is possible infrastructure for gas will be reduced in 20 years, but I doubt it will be anything noticeable to almost all people with gas vehicles.
As of Mar 2019, percent of electric vehicles sold in US was at 1.8%. That means the majority of fossil fuel cars sold in 2019 will probably be around in some way in 20 years (cars generally last much longer these days).
Doing the same math for most American states will punish the Tesla.
