Could be that Robert has a snag on the comeback trail , as his insurance , apparently based on his not being able to drive in F1 , was paid out some time ago .
I read he was offered a Torro Rosso ride in Austin , but a one-off drive would have triggered a potential need to repay those insurance folk , thus was not worth it , even though the chance to show well might have lead to more potential for offers .

A comment after the article summed it up well when they called it a paradox , that he was still being hampered by his injuries , as they were the reason for the payout , and that was the reason for not driving .

I have no idea what the payout was , but it raises the question of whether a real contract would mean his wages would be garnished(if that's the proper word) , although it would likely just be covered by a sponsor , I'd guess .

Curious situation .
