Query: Detects animals, not vehicles

I have a long driveway and wanted to know if a vehicle was approaching the house. The sensor picks up passing animals and pedestrians but has yet to register a passing vehicle, whether large or small. I have tried it at different locations and heights but it still ignores vehicles. It seems to work well for monitoring animal movements but, sadly, is useless for the intended purpose of alerting when a vehicle approaches.
