Thanks for playing and commenting. All good points.
The TTS voice doesn't run through the game engine mixer so I had to improvise a quick ducking. I can definitely improve on it.
The wind/tires sound does pan with the turns. I guess not enough. That can be easily dialed in. I was being cautious because I have been repeatedly warned of the opposite. My hearing isn't very fine and I tend to overdo those pans. XD
This was a quick and dirty 2-day job and I definitely want to continue to develop it. Stay tuned.
Maybe this will merge with SLATS into a road trip...
