The car is so stiff on the road it looks almost dangerous to drive, particularly on the straights.
Every time they showed Lewis on the main straight with the DRS open, the car car was literally dancing side to side it's so non compliant with the bumps on the track.
Martin Brundle also noted that it seems like the car is so unruly that Lewis was actually having to "drive the car on the straights".
It makes me wonder what overtaking will be like when opening the DRS seems to make the car so unbalanced.
