Umm, so they are implementing their version of a Vroombox?
Am I missing something here or are they seriously going to implement something so cheesy, so corny, and so incredibly stupid? And on a Fischer for crying out loud.
What?

Paul34,
Try using that pile of ground meat behind your eyes...Idiot. One problem that has arisen from the use of Hybrid/Electric Cars on the road is that lack of noise they make at intersections as people who are BLIND use the engine noise to determine if cars are stopped and if they are moving what direction they are moving in.

Hmm, well, I suppose that the fact you have not thought your post through is evidence enough of your lack of maturity - but the childish insult made it clear enough. Maybe you might want to graduate middle school first, ok?
At any rate, perhaps you have not heard many modern vehicles. Cruising at speeds on streets where pedestrians also are, most cars do not make much noise already other than tire noise, which any car - regardless of tire-connected motor choice - will have.
While the increased silence is a concern, it isn't anything new. Being blind and crossing a street without assistance is still going to be fundamentally risky, no matter how one tries to portray it.

The noise from ICE at idle is still far more than an electric motor that is not spinning.
It is true that most modern cars have reduced noise levels INSIDE the passenger to the piont where road noise (tires) are now the main complaints from people. Outside of the car, the motor of a car can be heard quite clearly. I know...I walk around LA during the afternoon rush hour. try getting oput of your car and listening.

That's fine, but you are not taking into account that the "danger" here - a moving, cruising vehicle - is not going to exhibit that engine noise you believe is there. Tire noise quickly is more than an engine purring at cruising, city street speed.

I'm sorry but this is such a "duh," tritonofg.
What you hear when a vehicle passes at anything over 10 mph--unless it's a Harley, muscle car, modded Civic, or other loud-for-the-sake-of-being-loud chest wig--is tire rush and air displacement.
Many hybrids (Honda's, GM's "mild" ones) can't even accelerate without their ICEs running, and even those that can still whine and whoosh as they're regen-braking to a stop (and usually use both power sources to accelerate, unless it's parking-lot-gentle acceleration).

PJ's right. I don't remember where I saw the study but whoever did it concluded that 70-80% of all road noise is air escaping from beneath the tires.
