If possible I would always attach a rope to the top of the tree and pull SLIGHTLY with a car. Not too much or it can split the tree as you are cutting it. When the tree is just about ready to fall have somebody drive the car away, pulling th etree with them. Do not do a wheelie, 10k an hour is heaps. Make sure that the length of the rope attached to the tree and the car, is longer than the height of the tree. :) This method overcomes any tendency of the tree to follow its own weight as it falls, as it will always follow the rope.
I was a tree lopper in suburban Brisbane for about 10 years so I know a bit on this subject. :)
