Add Hans Joachim Stuck (not-too-successful F1 driver of the early
'80s, pretty successful now in touring car series, also won this
year's 24h race at Le Mans in the GT category, IIRC) to the list of
real world drivers that have seen - and probably played - GP2.
There is currently some car exponation in Germany, and Stuck was
interviewed there sitting in a formula car transformed game station.
On the monitor belonging to that car, GP2 was running. He didn't say a
word about the prog., though.
