I'll never understand people that don't store their car in the car hole. People I know have had so many preventable problems that cost a TON of money.

Things like:

• Prematurely worn gaskets and seals
• Chipmunk/rabbit/squirrel-eaten wires
• Mauled by bears that get trapped in them
• Clogged roof drains that flood the passenger compartment from just rain
• Tires rotting and blowing out early
• Plastic wearing and shattering
• Paint fade
• Resale value decrease
• Smash-and-grab break-ins.

Wear is cumulative.

Most of all, the fun when the next hail storm destroys it, as hail is more frequent in more places across the US now, and insurance doesn't pay enough to replace it, or ceases to cover the damage. Good luck replacing it with today's insanely inflated car prices, at that.

That being said, I'm sure they've considered the trade-offs, and having space for everything can be hard to allocate. Some houses have very stupid designs. Also, in the context of electric cars, not really sure putting a lithium bomb in the house is smart. Whole house backups are installed on the exterior walls for a reason.
