You are a long way from great orthopedic, spinal or brain specialists. Young (or not so young) folks on two wheels in totally unfamiliar environment with bad roads, lots of sand, cows, cars/taxis going too fast for those roads, rum,,are not ideal conditions to rent a scooter. A couple weeks ago our best friend's son had a freak bike accident on their property ..skull fracture, sub dural hematoma.. Referred immediately by ambulance to a pediatric neurosurgeon in a speciality center handling children problems only..to evacuate the hematoma. He's doing fine and seems none the worse for wear..indeed while recuperating suggested his Mom take his sister for a bike ride when she was arguing with him.

Anegada is not a great place to do the scooter thing imho..and there are some residents there that can confirm that to be the case. Have a great trip..
