A Song for My Valentine... One

My funny Valentine, sweet sonic Valentine, you make me smile when I drive,
Your hits are graph-able, for the mathematical, you work so well in my car...
If I hear your little beep, and thereÕs no one on the street, I have learned to be discreet, brake real hard
Now-- bogeys do not snare me, you take good care of me, my Valentine stays!
Each day is ValentineÕs day....
