Walking in Waterloo Region

There probably isn't one. It would be very rare (I'm not saying it definitely doesn't exist anywhere) to have a signal for automobiles that is activated by a button.

Ah, but there is! It's an inductive loop. A presence detector.

The button is a presence detector for humans.

So, I guess we can call inductive loops for cars Beg Buttons, too, since the car has to "beg" for the light to change!

(what I'm getting at: I think the term is ridiculous)
