if you aren't doing road trips much you won't.
When you don't do road trips you don't need any infrastructure at all except your own house
Especially when compared to owning a second care with an ICE just for the occasional trip.
And then there is my friend on a fixed income that's realized it's cheaper to rent a compact car for long drives. Same as above because having the car break down in nowheres is expensive quick.
2. Cost: the rental cost is actually only a small portion of the cost. Extra insurance and other fees end up more than the rent itself.
Your car will depreciate regardless of that road-trip, just by virtue of time passing. Rental companies won't subsidize the wear and tear for you, so you have to pay that anyway.
