Why can't we look up to 90°?

[LeoLupinos]

Many little details in this game bothers me, one of those is that when I want to look to something tall, I can't, and I need to move away to be able to see the top, while in the same situation in real life I can manage to look up 90°, even a bit more behind me.

Can SE lift this limitation, please?

@Edit: I played some games that can do it by changing the axis to the camera when it touches the ground, instead of sliding, so that it can look up 90º. I think this should be the solution, works perfect in other games.
