How can I visually conceal a crack in my concrete driveway?
There are really only two solutions from a aesthetic standpoint:

Coat the entire slab with a surfacing product (which may or may not conceal the crack for the long term--depends on seasonal/traffic movement)
Replace the slab

You can't visually &quot;fix&quot; cracks like that in concrete. The color and texture will never match well, making the situation much more conspicuous than it is now.
