mdmx, you are right about realistic FOV, but I think you have one screen FOV backwards. If the FOV is really small, then the sense of speed is not very good. To get a sense of speed, the FOV needs to be as high as possible (for one monitor) so that the peripheral vision can see more of what is going by on the sides ie. trees, fence, wind turbines etc. Therefore, if the FOV is small, then less can be seen in peripheral vision, making sense of speed diminish.
