Although my sprite has a polygon collusion mask and that’s also convex.
but my car act like it has only the default hitbox.
My car has physics2.0 behavior

It’s not a bug. Physics 2 behavior has its own collision masks and is not using these hitboxes. You should edit the polygon in the behavior properties 
(I know that it’s not intuitive, but don’t have a better solution for now)
Confusing indeed, maybe add a warning?
Ideally in the default hitbox window when Physics is enabled for that object, “warning: the default collision masks don’t apply to the Physics behavior”, or easier to implement, a red line on top of the behaviour settings, “warning: this behavior uses its own collision mask”?
