Minecart wrong scan adjacent exit areas.

When in minecart I clicked rmb, I was teleported to adjacent area. Then I removed blocks of this area. When I tryed again, I was teleported in other area. But I cant "select" area by this method, because minecart searching scanning (2x2, when right-click in the minecart) only 2 sides of 4 possible: sunrise and left side when look at sunrise. It's annoying. Players makes minecart to move when collide (on rails). Thanks
