As with everything else money will rule, up to a point, in choosing the drivers. What will be interesting to see is which American companies can be lined up for major sponsorship. Shell (Ferrari relationship) may ace out any American oil company for primary perhaps, just speculating.
It provides an opportunity for the best of American technology companies to contribute not only money but their expertise in the development/logistics/operations/data etc. Would be nice to see some defect from foreign sponsorship to support Haas (I'm looking at you UPS, Microsoft). Or someone like Gates/Buffett step up (fat chance).
Now Paul Allen could be a good prospect. He seems to want to do legacy things with his bux (SETI, oceanographic research, et al). wishful thinking I know but it is going to be interesting to watch to see who really cares.
