comment Smooth replay of gps points on google map
you need to clone your line every 20 vertices to improve the refresh speed, your line will have too many vertices and slow the animation down.

Spawn a new polyline every 20 vertices, because updating a 100-vertex poly is too slow... play with setTimeout("animate(50)",2000); // Allow time for the initial map display
