When you have raced enough, it really does not annoy anymore, speed is 9'o clock or 12'o clock, that turn is bit below 9'o clock entry and you can enter to that corner bit over 9'o clock, it really does not matter what it shows it is enough that I'm in right range, then after few laps I get what is maximum safe speed with my current driving and work it from there.
For pits it is easy too, that number that looks bit shorter than next must be 80kph so I better stay bit below of that
Well, it would be nice if speedos would be made bit more clever, one of my cars has speedo from 20 to 200 kph numbers are 20 40 60 and so on and there is line without number between them, but even it is fairly clear and has lot of empty space, when put into tiny computer screen that has more fov than is realistic for such narrow area it would look quite unreadable.
Now do we like to get unrealistic speedos or should we accept that we have to use virtual speedos to see speed or decrease fow to something that is impossible to drive with (something like 23 degrees should be closer to reality)
Decisions, decisions, I would prefer to have realistic speedos and to use virtual speedos if needed, that is what I sometimes do use, specially for videoclips it is good as then it is possible to see what kind of speeds one drives.
Certainly simple thing is not so simple after all.
