Helmetvisors...

I been thinking about the tape some drivers are putting on their visors, Is this to make their vision a bit smaller, and maybe have less visual impressions from the sides during the run...?

When I drive the FC (Well, I`m trying to...still learning), everything is just a blur the 1st 2-3 seconds, and maybe its easier to see if you have a less field of vision..? Less blur? Eh...?

What do you think?
