This is my design for the Racing HUD. I included the key display elements:
The minimap is very simple, highlighting the roads in light grey and the current selected route or race in yellow.
The outer gauge shows the car’s current RPM and the top number is the current gear. The inner gauge and lower number is the speed.
The lap number or street race percentage progress as well as the player’s current time are shown on the top right. The position of all of the race participants is briefly shown on the right when laps are completed or race checkpoints are reached.
