Actually, while DH has pretty good map reading skills, he doesn't usually use them. He has a "mental map" and if that fails, we get lost (cos he is so lost that I can't find it on map). He sometimes uses the sat nav too.
Meanwhile, I DON'T have the same mental map. So I cannot immediately "know" exactly where I am going and how to get there. But I tend to be pretty good about knowing a route once I see it, figuring out as I go where I need to change etc (my mental map works on tracking as I go rather than seeing it all ahead of time), and if I really don't know - I check the real map before I start. If I get lost, I stop and ask directions. I have been given the sat nav for certain journeys (not that I WANT it usually), just in case.
But I will head off into the unknown, do long journeys alone, drive abroad (although I usually let DH have the first trip :o ) and drive at all hours of day and night, without any qualms on the part of either myself or DH.
I prefer to let DH deal with builders, technical stuff etc (he's an engineer, as well as male), but I am WELL capable of holding my own with such people. In fact, I have been known to pick up on things that the professional tradesman (that we're paying) and the resident engineer (DH) have both missed and that have been rather vital details. takes the eye of a woman 
And I am another woman who knows how to use an sander, and definitely not gay
