This quote from Paris comes to mind: "Faster than light, no left and right."
I always assumed that warp speed is so fast that they can only go in 1 direction, and cant make any course corrections until they drop out of warp.
Wasn't that line contradicted in a load of other episodes anyway? It was just put in to explain that week's bogus technoplot.
Perhaps.
But if you think about it, it does make sense. If you have a vector traveling at incredible speeds. Any deviation in the vector even by a few degrees would likely cause it to crash into something that's in the line of the vector.
