In Israel, this strategy is used as a high speed deterrant.....being more economical than Radar, Cameras, or Police.....

When drivers pass by, they slow down to avoid vehicle damage.....these 'pot holes' are moved around every day!.....

Should we try them??......or are our real ones on Pacific Hwy, sufficient  deterrant...?

Ha, fake news. Was an advertising campaign.
