With that, I started thinking in this mod and the R34 racing down that Irohazaka map (that BTW that mod needs some AI work ) at full speed!
This mod looks amazing! I'm surprised that it's so recent considering there's been a Russian AE86 mod for a long time.
Oh wow I get it because it's the car from the cartoon show. WOW! I don't think ANYBODY else has thought of that one yet!
Seriously thinking though, if you ever want to add the speed chime (as a option of course) then I think it is certainly possible, some of the plane mods have it so the plane knows when it may crash or not (with a sound playing), and I think coding the plane to be like that would have been quite hard, and the SBR4 has the auto spoiler at the back, which activates at a certain speed, so it makes me think, if those are possible then it would be possible for a sound effect (speed chime) to play when passing 62 MPH (or 100 KM/H) that is if you can find the sound for it without the engine noise atleast. Just a recommended thing and asked quite often but it may work.
