I hate noise more than most people. And I don't walk along--or drive along--texting or doing anything that distracts me from what's going on around me. But what I think about noise depends on what kind and why it's being made. When it comes to the noise generated by combustion engines, we've all gotten used to certain levels telling us that a very large dangerous machine is nearby, one that could kill us. Then there's also the consideration that not all of us pedestrians are young adults who are energetic and capable of sprinting out of the way. Some of us all little kids, some of us are old folks, and some of us are in wheelchairs.

I am sure there are certain types of noises allowed, but imagine once modders get their hands on this?  A Tesla modelX that sounds like a Ferrari, or a Big Block Cammed out Civic?  www.rolltone.com

While were at it... Maybe it should tear up the road like one as well. ;-)

I'm really not a a fan of making personal responsibiliy everyone elses problem.

This creates the complicity that feeds back on itself perpetuating the problems.

You're supposed to LOOK before crossing the street.  How will this work for a deaf person?  How will this work for someone wearing a headset and listening to an MP3 player?  No matter how, it should not be the responsibily of the vehichle manufacturer....

We are used to vehicles that make noise so now we HAVE to make noisy vehicles?  If we can get used to vehicles that make less noise, Darwin will prevail.

Believe me.  I get it.  But how much noise it too much?  If all the other vehicles on the road were quieter, I don't think this would be a problem.

I think we might want to have a poll, and let the readers of Design News provide their input on the most appropriate noise.

I want to propose that all hybrids and electrics must play the Beatles "Instant Karma" at 115 decibels.  Especially late at night in residential neighborhoods.  Can't be too safe!

As I mentioned in my comment "way back," if the expectation is that you must sacrifice the positive features of a car, such as its quietness, to make it safer, then there are no limits to how safe you can make it.  You can add two tons of safety equipment so that it can no longer go any faster than 10MPH, and cost $100K.

You can't really protect the stupid. If you could NO ONE would ever be hit by train. No matter how hard you try they will find a way around your protection mechanism. When they make me dictator I will require that bicycles should all be required to have playing cards clothes-pinned to their frames to flap against the spokes.

I want my Prius to sound like an Abrams Tank.

I remember when I read about the Toyota initiative to include a speaker, I thought it was an ok idea. But when I was blindsided by a few EVs afterward, I thought it was a great idea.

This reminds me of putting cards in my bike spokes as a kid.
