LOL... now Mr. TT has all the same information 3-TIMES!
1. In-Cockpit
2. HUD in-game
3. Smartphone app
But,..I tried a different hud for my smartphone too. Because I think it is an awesome idea!
What I found out:
1. I never found a proper place to install it somewhere around me.
2. There is no real benefit I got from it.
The best Display is the one in front of you. In the car you drive.
