Kevin Magnussen says drivers are left "blind" to cars behind them, saying the issue was partly to blame for a recent tangle with Charles Leclerc. Haas driver Magnussen was branded "f***ing dangerous" by Sauber boss Fred Vasseur after swiping across Leclerc's front wing.
Leclerc called Magnussen "stupid" after his late move at Suzuka cost the Sauber man a front wing, while also leaving himself with a puncture.
Both drivers ultimately retired and Magnussen escaped sanction, however FIA race director Charlie Whiting later revealed that he thought the incident had been worthy of sanction.
For his part, Magnussen agreed that his defensive move had come too late, but said it was down to being unsighted.
