I thought you were joking... until I saw the video. It looks like a huge bright curtain with a 15-foot tall STOP sign unfurls in front of the driver! Whatever the cost, I'm sure it's paid for itself already.
- londons_explore 6y agoIt should be possible to design a sign like that pretty cheaply... Just a toilet flush mechanism to a pipe with thousands of holes spraying downwards, and a bulb, lens, and plastic film for the logo. The bulb would be a few of those football stadium arc lamps. One kilowatt per square meter is sunlight brightness, so you're going to be needing ~10kw of lighting. The whole system, complete with installation labor, probably $30k. Most of that is in mechanical supports for the water system. Except, government being government, I bet this was a $10M contract awarded to someone's mate...
