Re: The HUD of some ships really have me Worried.
Also, take a look at the design of a TIE Fighter, TIE Interceptor and TIE Bomber. You really don't have a view of much more than what is Directly infront of you due to these big solar panel on either side of the ship.
Let's go for an in-canon explanation. The Empire expects it's pilot's to be the best of the best, and make do with the cheapest built fighter in the galaxy. They don't even give their ships shields.
If you go ahead and take a look at the Rebel Ships the A-Wing, X-Wing, Y-Wing, U-Wing. You'll notice they have a GOOD field of view, especially the A-Wing. In-Canon, they take all the pilots they can get, and give them every advantage they can.
You wanna join the empire and fly TIEs, you have to be THE BEST, this was the case with XvT series, this will be the case for Squadrons.
