Simple and effective method (some police is using too) how to measure the side distance to an overtaking car.

I don't know how it is in America but in Germany I also wish we'd have more radar traps and more undercover police to care about this problem.
In Germany the populousness is much higher than in the US so it's generally more important to follow the rules.
Thank you for your feedback!
In my first test I also noticed that the cars are too fast and my sensor is too slow. Because of that I tried to get the perfect refresh rate - as shown in my code.
With this rate it's refreshing fast enough if the car is moving at a max speed of 50 km/h (31 mph). Usually that's the speed limit in german cities.
Of course. Unfortunately I don't have a 3d printer. Like you see at the pictures, there is some space left inside. Moreover you could use a smaller display, not breadboard and even a smaller Arduino, if you exclude the leds.
