Ken,
If I could have a Ferrari with a kick-ass audio system and an engine that made no noise, I'd be the happiest driver on the planet. Even in a traffic jam. Cranking Rush's "Red Barchetta" with nothing, but the sound of the tires, wind and a slight whir from the electric motors would be a lot of fun at 80mph.
Now, I'd also have to be able to afford the service and maintenance of a Ferrari. That's a bit too steep for me and most people.
Given that the fastest road cars in the world are now electric, I think it's time to give up the growl of the engine for the roar of the audio system.
