I'm guessing the tail light wires on the Toyota are 22 or 24 gauge. No
problem for the application but considerably smaller than on my old
('86) pickup.

I have no complaints with the car but it is not over-engineered as was
typical in Detroit's golden years.

Over-engineering is not good for the world as a whole.
To do it "just right" saves on resources.

Also in a modern car thje tail lights will be LED and use less power, so
the wires can be even thinner.
