I am sometimes worry EV too quite that pedestrians and people riding bicycle can't hear the car is coming. I suggest Model X to add imitated tailpipe or fog light which is actually speakers. It can produce V8 or V12 engine sounds, or maybe automatically activated when moving objects nearby are detected. The volume can be adjusted manually will be useful, and the function can be deactivated if no need. Also those speakers can be used for outdoor events, like going to beach, BBQ, outdoor parties, etc. or for election broadcasting car. Since the tailpipe is usually long, it might be very effective when designed as bass reflective chambers and should produce loud and deep solid bass too. If Tesla finally doesn't provide this option, I would like to make this for Model X. Anyone want to develop this product together?
