Because of how truly enormous some of the gals can get on a near daily basis, it’s more than likely that they’re capable of withstanding a few extra pounds weighing them down from the front, back, or all around:

Eden: Despite the fact she absolutely detests the concept, Eden is able to carry tremendous weight due to how thick her legs have gotten as a result of her growth, and considering she lugs around over a quarter of a ton behind her, a person atop it wouldn’t make a difference.

Kara: While sitting atop them would be unconventional like with the others, resting between Kara’s breasts would allow for a comfortable and convenient means of travel, just be sure to not get too lost since I doubt she’d be eager to pull you back out.

Mei: Being the largest Hyper in all of New Primrose, Mei has access to a wide variety of social services, one of the most notable being experimental hover-pads fastened to the undersides of her colossal breasts, allowing her to haul around the metric tons of boobage around without a hassle, with any added persons making barely a dent in how much can be lifted.

Cassidy: Similar to Eden, the thickness of Cassidy’s legs allows them to drag their meaty body forward in spite of how much they weigh, with any added cargo doing nothing to hinder their waddle.

Renée: In spite of how ridiculous their titanic frame appears and how much she weighs, Renée moves with unprecedented grace and precision whenever she makes her commute, and could willingly serve as a mode of transportation with much potential space of passengers.

Cornelia: Considering their occupation revolves around ensure the safety of others, Cornelia effortlessly uses their gargantuan flutes as both a flotation device for to remain afloat as well as a makeshift raft to haul distressed or injured beachgoers from the water.
