No, it doesn't work like that.

The rubber composition, and tread patterning, on snow tires are categorically different from summer tires and adjusting pressure and whatever "handling characteristics" are won't give you the same level of control in snow.

Plus the tires wear down entirely eventually.

For the 12v battery, theoretically an EV could pulse-recondition an underperforming 12v battery, though I doubt any currently do.

There's a big difference between someone thinking software can solve everything, and pointing out that software has already solved some things, and the opportunity exists for it to solve more.
