Blanket realism is not fun. By that I mean many aspects of the real world are not there for fun, they exist/happen naturally, or they're a human construct that is part of modern society. As an example, cars needing fuel or batteries charging is a natural aspect of our current reality that is not fun. We'd all love to not need fuel or recharge batteries. Paying to refill our cars, road or otherwise, is not fun or in any way a positive thing. We do it because we have to.
In a video game, even a simulation, you get to choose what aspects of the real world you simulate. You do that, one would hope, by choosing aspects that are fundamental, fun or hopefully both. For example, you simulate all aspects of real world driving, even negatives like understeer and brakes locking up, because they're a fundamental part of driving. You can also easily argue it's fun to try and avoid them. Cars driving with none of the flaws of real driving would be less fun, even if the individual aspects are not fun, per se.
Wear and tear is not fun. There is nothing fun about things wearing out, it's an aspect of realism we'd eradicate if we could. Nobody enjoys their clothes getting worn out and getting holes, nobody enjoys the tyres on their car wearing out. 0% fun, 0% entertainment. So why would you include that in a video game, made for fun and entertainment?
PD obviously understand this. They don't make us pay for new tyres every few races, or buy fuel, or pay for car insurance, because none of those things are fun or bring anything positive to a video game where tyres and fuel are just lines of code. They'd just be a chore and expense, two traits you don't want in a video game if you can help it.
In short, they should not be including things solely for the reason of realism. As said, you need to also make sure that element of realism makes for fun and entertainment in a video game, even in a little way.
Nothing about this system is fun, or entertaining.
