Unfortunately electric cars won't solve that problem. The graph on http://www.leiserstrassenverkehr.bayern.de/laerm/entstehung/ http://www.leiserstrassenverkehr.bayern.de/laerm/entstehung/ (a German government website) compares the engine noise ("Antriebsgeräusch") with the tire noise ("Rollgeräusch") for different speeds ("Gesamtgeräusch" means "total noise"). The yellow line is for trucks, the blue lines for cars.
As you can see at a speed of 40 kph (25 mph) a car's tire noise is already higher than the engine noise and at even higher speed the engine noise doesn't really matter anymore. So even if your electric car engine is absolute silent, the total noise at speeds above 30 mph won't be all that different.

- barclay 11y agoUntil they went for these bloody 6-cylinder turbos that the formula is using now. They're nowhere near as loud or as impressive as either the v8's of the 00's, or the v10's and v12's of before. Even being televised, they've got to jack up the volume to try and make it seem more exciting.
