There has to be a market for a company to add a V12 sound to the Tesla S.
I'm sure it can be done but the question is whether someone wants it. Many in that class would probably adjust quicker to the silence of EV's than a lie.
Do keep in mind that engine noise is not only beneficial to the driver but cyclists, other motorists and at crosswalks as well.
It's not a problem that is easily solved and satisfied by all parties.
We have to do everything in our power to make sure cars don't have "ringtones".
No, seriously, I think you do the blind a disservice. I don't think that blind people rely on, "Hey, did I hear something" to mean, "I can blithely cross the street without danger."
Cars are smaller than trains.
As a pedestrian, I disagree. Cars make far too much noise. People will adapt to them being quieter by using their eyes and looking both ways. I look forward to the day when living in a city doesn't mean hearing a constant drone of traffic.
