Wait a minute ... do the new electric cars not have horns?

[GAB-1955]

Perhaps the real reason some people hate hybrids is their silence. They can’t gun the engines to impress themselves and annoy their neighbors.

Fact. Drivers and pedestrians are both used to the idea that internal combustion vehicles make noise you can hear when they approach. These vehicles don't, and people have already been killed due to the silence, and people being surprised that the vehicle was there when they didn't look first. (Why look? There can't be anything coming, you would have heard it. Dumb perhaps, but people make mistakes like this out of habit.)

In the Chicago Loop for a while they had bus-only lanes that went opposite the one-way traffic (buses in this lane went one way, all other traffic in the other lanes went the opposite direction). They took them out - people were getting killed because they were used to one-way traffic and kept forgetting to look for the buses going the other way.
