I think there is a difference from the game. The disc for the game costs the same to produce regardless of whether you buy the DLC or not. The larger battery costs more to produce regardless of whether you pay for it or not and (slightly) hurts the performance of cars that don't have the upgrade (it's literal dead weight).

I guess I don't really care, especially if there is good disclosure for expensive physical devices (because I can then not buy them).

It is definitely different which is what makes it interesting. Since you're maybe getting something you didn't pay for. On one hand, it is dead weight if you can't use it, which is even worse (since it degrades performance) but if you can jailbreak it you get it for free. But either way, it definitely has a real physical cost, it's not just code.

It both helps and hurts performance. The added weight will hurt handling and efficiency, but the increased capacity allows for increased power output. This is why the 90D has a lower 0-60 time than the 75D, for example. The new 60 has a quoted 5.5s 0-60, whereas the original 60 (which actually had a 60kWh battery) was 5.9s.
