Cape Town - Valtteri Bottas had no issues related to Halo during a recent race simulation in which the cockpit protection device was fitted to his W09.
Ahead of the 2018 F1 season - the first with Halo - Bottas has been in action in Mercedes simulator at their Brackley headquarters.
The Finn revealed that he covered a full race simulation with Halo and found that he adjusted to it very quickly.
"In the simulator I've done a race simulation already with the Halo, and I have to say during the race I never noticed it anymore," he explained in the latest episode of Motorsport.tv's The Flying Lap.
"Once you get used to it it's there and you get used to it, I think that's going to be the same for the spectators."
The Mercedes driver added: "Initially, it's something new, it looks different - some people say it's not nice at all.
"But I think it's only a matter of time everyone will get used to it, and if it can avoid even one injury - big or small - it's a good device."
