Straight line measures crow-flight miles. On a normal city grid it lands close to fair. Across a canyon, a bridge, or a freeway with no on-ramp, the crow wins and you don't.
Drive time pulls real venues near the straight-line answer, asks your routing server how long each person would actually drive to each one, and picks the venue where the real minutes match your requested split most closely.
