First of all I would ask for implementing in-car sound dumping. It should be additional parameter for car makers, making possible affect external sound characteristics while driving from cockpit. Additionally, setting up loudness of other cars sound (listen from cockpit) for mod, it will not affect external cameras sound. Dumping filter might affect not only loudness byt also contain some filters (I think lo-pass would be enough) Second thing I noticed in beta, is improper sound reverb. It sounds like some fixed reverb params are used. In real live various materials reflects sounds in different way resulting various reverb effects. Driving in tunel we hear engine other way driving through a forest. etc. I'm not saying that those effects should be simulated by physics or at least based on material types, but it would be enough to give some reverb attributes to be set by modder. with regards
