It is not that you can't know where you are going or how fast you are going. Heisenberg says that they are complementary metrics. You can know where you are going if you do not know how fast you are going -- actually, momentum, which includes your mass.

Also, the extent to which you know your momentum, is the extent to which you do not know the position.

The two metrics -- momentum and position -- are complements, in the mathematical sense. Similarly, time and energy are also complementary. But I won't go into that here. Too much woo has already been woven around that theory.
