This is patently absurd. I agree with Marketing. Someone who is completely deaf would not be able to hear a diesel truck coming much less a hybrid.
I am surprised they have not called for the same thing on electric golf carts.
Do we really need legislation to protect those unfortunate folks that that are hearing and/or sight impaired? What's become of our 6th sense...common sense?
Since our legislators are dedicated to protecting those unwilling to take responsibility for their own actions, perhaps a better solution is to develop low range sensors that transmit logic, judgment and intelligence into those that have been relieved of their senses. These novel products - call them "Common Sensors" - should be mandatory equipment installed on all legislators.
Its taken them this long to figure out that there might be an unintended consequence?
Personally I think Darwinism should be allowed to play its course and then in a generation it won't be a problem.
If that is too radical for the conservative right pro-lifers who don't believe in evolution then I think your idea of playing cards plus clips is the way to go.
I can see it now: I'm driving down the road when, horror of horrors, I see a policeman pointing a device at me. Nope, it's not a radar gun, but -- gasp -- a microphone! The policeman pulls me over and speaks those words that I was dreading to hear: "Sir, you were driving 10 decibels below the sound limit. I'm going to have write you a ticket."
Kidding aside, the "too quiet" car can pose a real problem. It will be interesting to see whether regulators simply mandate a minimum decibel level or whether they insist that the car makes a certain kind of noise. The purr of a well-tuned Porsche, perhaps? The skirl of a Honda S2000 as it starts to redline? Actually, carmakers should see this as a business opportunity: Cellphone users spends millions every year downloading custom ringtones. I'm sure people would spend an equivalent amount of money downloading custom engine sounds for their electric vehicles. Why settle for a dreary hum when your electric vehicle could scream like a Lamborghini at full throttle?
