There's some interestin brain stuff going on for some of it. A person with failing vision (and dementia can cause some loss of vision even though the eyes and optic nerve work fine) will learn the layout of their home. A care worker comes in once a day and moves something? That person falls over.
Someone from my local MH trust realised that people with dementia in hospital could not see (because dementia) the zimmer frames and weren't using them. He painted them red. This means people can see them (red is one of the last colours to go) and thus they use them. This simple measure has reduced falls and the associated deaths and injuries.
The population of the US is roughly 310 million people. Using your figure for driving fatalities, 3.1x10^8 / 2.5x10^4 = 1/12400 chance of dying in a car accident. This tracks reasonably well with the admittedly outdated information in [1], which gives the odds of dying at home as 1/7875.
By your reasoning, then, my apartment is about 33% more deathtrap-y than my car, and I should probably consider living out of doors, as well as giving up my car and staying away from roads.
Except that, from the same data, my odds of dying at the hand of another person are about one in sixteen thousand. I live in a large city, so my options are starting to look pretty limited! Subsistence farming may be the only way. (Or perhaps hunting and gathering -- this is prime whitetail country, and there are few enough hunters for deer to've become a serious pest through overbreeding.)
All life is risk, and the outcome is known ahead of time - the probability of dying of something, given long enough, eventually reaches unity. Maintaining a healthy sense of perspective seems warranted.

And almost everyone has a home every day, whereas people who drive/ride cars more are at mich higher risk of car dying than less-frequet riders
That number is highly biased towards the elderly. "Falls" are basically another kind of "died of old age". If you exclude people over 55, you get about:
- ~6,700 deaths from drunk driving
- 2,459 from falls
If you look at all driving fatalities (because we fleshy humans can be impaired by more than alcohol and often make mistakes), you have
- 25,499 deaths
Cars are deathtraps.
