Intercoms are legal on bikes, so I can't see how they can be legal in cars...

I agree that in the M3W an intercom is possibly essential, in Aldermog conversation is easy up to about 60. I lined the cockpit with Dynamat acoustic insulation and it made a big difference...

As others have said the engine/exhaust note is part of the experience. Shouted conversation isn't!!
