Seems great in practice, but wait until someone with the slightest hint of paranoia misattributes a threat against their car, to a threat against their safety.

One of three things happen:

• Driver freaks out and freezes up.
• Driver freaks out and speeds away (possibly causing an accident)
• Driver freaks out and aims their car at you and puts their foot down.

I fashioned a large, hand held metal stop sign on a board. That’s why I carry when I cross busy streets in my neighborhood. I hold it out in front of myself like a flag. Drivers will slow if they think they might hit a big piece of metal. And drivers will bully soft fleshy humans with the threat of great bodily harm. It’s not very nice but it helps keep me alive.

Relevant video in which a guy stands still at the side of a road next to a pond:

• Hands free: he gets a lot of splashes by uncaring passing drivers

• Holding a brick in his hand: drivers slow down and avoid the pond.

It’s really funny:

As usual drivers care more about their car than other people’s wellbeing.

BTW: any shop that sells inflatable bricks?
