my feeling is the same as it has always been:
Making the world noisier is not the answer...making more things quieter is.
1. people with iPods and smart phones and bluetooth phone thingies in the ear are not going to hear you anyways.
2. why just EVs and hybrids. I have always driven a manual car. A large part of the time when I am going under 20 mph I am in neutral coasting. So should all cars make a sound when in neutral and moving??
3. Who is this protecting? You want to keep bicycles safe? Make more bike lanes. Require helmets. Enforce bicycle laws. I'm a bicyclist, and we have a lot of deaths here in Albuquerque (we have "ghost" bikes all over town...white painted bikes placed in memorial at every bicyclist's death)...about 50% are driver error (we have awful drivers here...like everywhere I guess)...and about 50% are bicycle rider error (we have awful bicycle riders here...like everywhere I guess).
for bicycles, noisier car's aren't the answer (or else we wouldn't have all these ghost bikes in town)...more separation of bikes and cars is the answer....better training of both drivers and riders is the answer...better protective gear is the answer.
for people, noisier car's aren't the answer...more attentive people (walkers, bikers, drivers) is the answer.
I guess I just have to make sure I buy my EV car before 2016...or buy some wire cutters...
