Project holograms of children playing on the side of the street, throwing on the road in front of reckless drivers to make them slow down. Leave plenty of distance/time for the drivers to react.
  • Reduce vehicle speeds in residential areas.
  • Make people experience the worst-case scenario of reckless driving without actual consequences.
How it works
A roadside radar speed sign is used to measure and show people their driving speed. Additionally, there is a camera/software that detects (drunk?) drivers who have trouble keeping their vehicles straight.
When a reckless driver is detected, a roadside hologram is activated. It can show:
  • less dramatic: a kid playing and throwing a ball on the road.
  • more more dramatic: a kid jumping on the road, being hit and falling back into a grave on the side of the road.
Do it 100-50 meters before the car gets there so that the driver has plenty of time to react.
There are number of hologram technologies that could be used to achieve this. Some are affordable, others expensive. Here is a video overview of the technologies.

The 7D hologram would be amazing for the purpose. But I guess the one I'm proposing is cheaper and more feasible for the time being. It's called "material fused holograms". This video explains the "Gatorade water hologram" technology and demonstrates it in action:

I would go for a simpler variant of this. A thin straight waterfall/shower would go off from a high-mounted tube with nozzles. A projector or color laser would project on the falling water droplets for a few seconds - just enough to get the message across. The event would be timed according to the driver's speed, so that people see what they need to.
The falling water itself is surprising enough to get the drivers' attention. The holographic story that unfolds will make them think for a while.

However, will this eventually not lead to de-sensitization ? If people figure out that they can drive through holograms without any repurcussions, they may do the same with 'real people', thinking they were holograms. I remember calling up the city safety engineer with enough signatures to put up 'Caution: children at play' signs on my street and he told me he could do it but there were so many similar signs that drivers would really not pay much attention. I like cameras that take a picture of your license plate and send you a bill in the mail. That is a surefire deterrent.

Shireesh Apte it should be tested and evaluated based on the results. Getting a bill in the mail has downsides as well. I've experienced this in Australia in 2004. I remember telling my friends back home (when there was still more freedom) that it seemed like a beautiful open prison where "people have tons of stuff but no time to use it and everything is regulated down to a fart."
Eventually, there came a time when my hometown was about to be turned into an automated punishment environment. People fought tooth and nail. Both the town major and the country's prime minister were ousted as a direct result of this attempt. What was left of the multi-million dollar surveillance system that was already installed was removed by the next major even though people ended up paying for it.
Some people love their freedom. There can be different solutions when low-hanging fruit is forbidden.

Could daylight/sunlight be a problem? I've never seen a hologram projected in the sun.

Agreed. People need a constant reminder of the consequences of stepping out of line.

Also, holograms of traffic police can be used to make people follow rules. Stretching this idea further, holograms of police cars can be implanted in different crime-prone areas of cities.
