Miraak could, like, leave traps and when another carter comes on them, Tentacles hold the cart back for a few seconds.

The Mudcrab Merchant could have a natural "bubble" around itself where other carters are harmed (the claws.) Or it could "buy" (steal) a power-up, (if we're doing power-ups), from another carter with like a minutes cooldown.
