The term you want here is "quadratic in speed", not "exponential".

If you really think that the risk is low after being hit at up to 10 mph, how about we run our Leafs into you at 9 or 10 mph a bunch of times, including making sure you end up under the wheels a few times?

You will most definitely sustain serious injuries.

I agree, "Correlation does not imply causation" because even if the injury rate is low, it says nothing about the circumstances that could have prevented the injury. So even if only a few people are being hit by EV a week because they don't hear the vehicle does not mean it is not worth the time and research to prevent those few people from being injured in the first place, even if minor by whatever standards they use to define what a minor injury is.

I would still just like to know the price for a DIY kit or a final kit before the thread is taken over :)

I'd like to know a price (ballpark) and understand the time to install before making a commitment, but I am interested.

I too would like to get one of these complete ready to install.
All this noiseless theory should be on another thread.
How many years have luxury car manufacturers aspired for a silent smooth ride.
Now we finally get close, and we get an artificial noisemaker installed.
Great Idea, I get it, but don't eliminate my choice and options.

Anyway, I WANT ONE, and a video of how to install it.
I would like a default on or default off option IN THE KIT if possible.
Yes, Ive been on here for 4 years, I've seen the default on, default off thread.

Thanks

I'm sure the OP has an excellent attorney working on a liability release document that purchaser will have to have notarized and returned with payment to purchase the product ;)

Of course if we shutdown everyone selling something that violates NHTSA guidelines, over 1000 window tint installers would be out of business :roll: :o

It seems like we have around twenty people interested at the moment.

Connectors and terminals come in around $15 and the factory switch is around $15 as well. Wire, heat shrink and strain relief will be another $10, but keep in mind I'm using all mil-spec material: Tefzel wiring, DR-25 heat shrink, and SCL for strain relief. Anyone doing it themselves can obviously use whatever material they would like. It takes an hour to build a harness, add another 15-20 minutes if you want it labeled with 3:1 heat shrink.

Count me in as one of the twenty!! :)
