LOL but isn't it sad that we even have to go to that extreme!
It is sad, but conducting the experiment is rather fun.
Experimentation Guidelines:
1. Hang out in someone's front yard doing whatever you do in the front yard
( a group is very effective for this endeavor to go on for extended periods of time)
2. Every time a car is going too fast down your street, yell at the top of your lungs "SLOW DOWN"
(this step is bit more effective if you have a loud mouth around)
3. Watch with joyful bliss as the driver tries to figure out what just happened
4. Don't yell and see that the results are different
( a control group is necessary in all experiments)
Now you could just throw roofing nails in the street, but said nails do not care what type of car goes over them. The PD have asked us personally to refrain from this drastic measure. I can understand why, but it is oh so very tempting.
