Just stick the batteries on an exterior brick wall, without anything flammable above them. Not easy to do in every house. But easy to do in a lot of houses.
A building near me has a commercial full-scale Tesla power bank (I suspect to run essential loads during power outages; they don't have any solar afaik). They just installed it at one corner of their parking lot. It's surrounded by concrete so if it ever catches fire, no big deal.

Connected garages aren't as dangerous as you'd expect. In most places building codes already require them to have significant fireproofing between the garage and the rest of the building.
Obviously, in many cases the build will pre-date said codes, or builders will cheap out. But this isn't an unsolvable problem.

I've seen videos of EV fires. I've also seen an attached garage fire with a non-EV car – it was so hot you couldn't comfortably stand across the street from it. The house still survived due to the cinder block wall between the garage and house.
Still much less spectacular than the natural gas explosion I once saw... The house that actually exploded was just gone, and every house around it had to be torn down due to massive structural damage. But that explosion was intentional insurance fraud.
Asbestos prevents fires from burning down your home or any building
