"I tried it this morning, I got a bit dizzy".
The new concept - a major evolution of the divisive 'Halo concept that tested at several events in 2016 - is being given its first outing at Silverstone this weekend to allow the FIA to gather feedback on the potential issues of visibility and aesthetics.
Grosjean became a director of the Grand Prix Drivers' Association earlier this season after replacing Jenson Button, and the Frenchman has revealed that the group no longer discuss cockpit protection, but admits there is a split of opinion about whether it is needed or not. After the halo system had faced criticism, FIA proposed the 'Shield' to protect the drivers from flying debris. I think it's because of the curvature, you get quite a bit of distortion, plus you get quite a bit of downwash down the straights pushing the helmet forwards.
"We had a run planned with it, but I didn't like it, so we took it off".
"For sure it doesn't help".
The Briton clocked a best time of one minute and 28.063 seconds in the opening spell before rain intensified with 20 minutes remaining.
It's expected that the Shield will get a little on-track test on Friday in Free Practice One.
"It should [help Ferrari]". "Obviously the test was not very conclusive today. I haven't seen much yet but it's fun to drive around here!"
