Coolant, throttle, heat, and JJ Bars are straight instead of curved all funny? I think that's an improvement.
If you look at those bars independent from the rest of the HUD, it's neither an improvement, nor a change for the worse. However
if you look at those bars in combination with the rest of the HUD it is
a change for the worse, because they waste more space. As already said, the old HUD was purposefully made this way.
Also, BA HUD is better now than ever before.
No one is saying it isn't.
