Advise for Motion Sensitivity 4 a Busy Street

I am trying to figure out how to finesse the setting to pick up a person walking by but not all the car traffic. Current setting don’t catch me walking to the car and driving away- which is not helpful as I am trying to prevent auto theft. So many little things to dial in, maybe someone understands this nuanced setting? Thanks in advance.
