Heard that the car trunk weapon storage theory is true

Saw on an IGN article that listed some features they experienced, apparently the idea that most weapons and outfit changes could be stored in the trunk of your personal car was correct. Also saw someone a few months ago on the same post to justify the trunk loadout feature theorize that in order to bring your personal car to you, you could use your significant other to deliver it, either Lucia or Jason, since unlike in RDR2 the cars can’t drive themselves. Which also seems to be true with the ability to summon your SO being shown in the trailers. Just funny to see considering the hate comments I saw on those posts either deciding the features were dumb or didn’t make sense.
