Hilton Tupman’s Pedestrian Horn

Los Angeles auto dealer Hilton Tupman wanted to level the playing field between motorists and pedestrians. So he invented a horn that pedestrians could use to honk at motorists. And he made it loud enough to be heard within a 1-mile radius.

Awesome! Although carrying that bad boy around, just to get back at car toots, might indicate an OCD tendency.

Joggers around here carry batons - mostly to discourage aggressive dogs. If it looked a little more intimidating - say like a sawed-off 12 gauge - a baton could even intimidate cars. In *certain* neighborhoods the police might even give you a pass - if you looked like you belonged there.

How long to pump it up to 500p.s.i. with a bicycle pump?

This horn looks like the perfect accessory for a protest. Even though it looks expensive compared to a vuvuzela, unions and organizations usually have the budget for that stuff. The automotive workers could even build one themselves!

@KDP I'm not sure the seals in a bicycle pump would handle 500 psi.
We have an industrial air compressor at work, but by the time I got home, I probably would have use all the air pressure up. I do like the idea though.
