2021 F1 Bahrain test de-brief with Scarbs
Only one pre-season F1 test in 2021, so there was lots to be learned and tried in Bahrain. I talked to Craig Scarborough after the test about new developments on the cars, the outstanding pace of Red Bull-Honda…and what appeared to be a disappointing test for Mercedes.

Ok why not take a page out of WRC and start a race on time? Each car starts from standing start~10 sec apart and proceeds to race against the clock and giving time for water to fall and clear the track over time. Just a thought.
