If you're happy leaving it to someone else, and they are happy to do it , fine. My caveat would be though, to make sure you CAN do stuff, even if you never think you'll have to. Otherwise, one day, you will be miles from anywhere, alone, with no phone, no one around and stuck. All the fluttering eyelashes in the world won't help then.
If I'm out with certain friends, I know I won't get a look in at a mechanical, because they'll be falling over themselves to fettle it. Not, I'm sure, because I'm a girl, but beause they're all keen macklers. As a result, they'll probably be much faster and more efficient than I would be. But at least I know that when I'm out alone, I can tackle most stuff I'd need to.
