Break-in periods are not as crucial as what they used to be decades ago. Any car that has over 1000 miles on it is already as broken in as it is ever going to be.
The driver getting "used to the vehicle" is nonsensical, unless you are a really disoriented driver.
If the tire supposition were true, then we should notice a
drop in MPG every time we buy new tires.
I don't believe any of those things have any effect.
