A little further to the comment about seats with HR (halo). I have been speaking with the designer/conceptualiser. The HR wings are designed in such a way that they should not be forward of the eye sockets, so that 90 degree vision is available without turning the driver's head. If the "wings" are forward of that point with helmet worn, there is something not right. I'm guessing that very few people have peripheral vision to that extent, so it's inevitable that the driver will turn his head, thus the eye on that side would be behind the wing. Awareness of other cars should be from proper mirror use?
Escape from the car.. if the HR is an issue, perhaps there is an installation issue?
