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.
