Norbert Haug has slammed as "ridiculous" the situation surrounding this year’s young driver tests.
The traditional late-season session scheduled for Abu Dhabi in November was called into doubt earlier this year due to the particularly arduous back-end of the 2012 calendar.
A test at Silverstone in July was scheduled instead, but Bernie Ecclestone reportedly threw a spanner in the works by reminding teams he has control of the venue in the dates surrounding the British grand prix.
Haug, German carmaker Mercedes’ motor racing chief, said the continuing uncertainty is "ridiculous".
"Frankly, it’s pretty ridiculous to waste time on such things," he is quoted by Germany’s motorsport-magazin.com.
