I so want this too, but foresee a potential problem with ‘ground-ception’ in nested vehicles… After all, I’d want a mobile base / death wagon with space in the back for holding & fixing up a raiding vehicle which itself has a coupla’ bays loaded with shopping carts for an extra speedy smash & grab.
Just park up the mobile garage base outside town, roll in with the raider, unleash a cart, load up with goodies and then tie it down to the bay and scarper!
Just worried that keeping track of which-floor-is-which could be an iffy proposition for the game prompting a new slew of vehicle-related bugs; but yeah, I guess anybody who’s ever seen The Italian Job or Knight Rider wants this as an option!
