After racing with my wife last night. I asked her what could be improved (besides my driving). She said she would like to hear more racing sounds. She stated the following ideas for more sounds: Cheers from the spectators, Car breaking sounds, car speeding sounds. I know there are programmable sounds, but have these sounds go off at "random" times. Ideas could be sounds could be triggered to braking or acceleration of each car or Cheering when a car passes another car, etc...
Also different sounds for each car . The cars with the same cylinders could have different sound characteristics (i.e. muffler, turbo, non-muffler). Tell me what you think.
