Design flaw: "mouse-maze"

In order to get from the LV1 tab to a LV2 tab(and on to LV3), the user must move their mouse cursor straight down and then straight across, if they move outside the boundary they have to start over.

They can't V-line it from LV1 to LV2 because they cross over part of another LV1 tab. This could be changed by adjusting the hover time, but then would be annoying transitioning between LV1 tabs.
