Front yard motion sensors pointed at the street is driving me nuts

I did a service call last week at a house in Oak Park and the homeowner complained about false alarms every night. Walked outside and saw the motion detector was aimed right at the sidewalk and road. The installer before me even had the sensitivity cranked to high. I see this at maybe 1 out of 3 houses I visit. Why do people think pointing a sensor at a public walkway is a good idea for a residential system? Has anyone else had to explain this to other installers on the regular?

Man I just read a study that said most false alarms happen because sensors are aimed at public areas instead of private entry points. The fix is usually just repositioning the sensor 30 degrees down and cutting the range a bit. You ever notice how the box instructions never actually show you the correct angle to mount them?

Points a sensor at a busy street then acts surprised when it goes off...
