I've been wondering about that this week OP, especially the bit about being regarded as a bit suspicious.
Have been looking at cars to buy for a while and since one particular model I'm looking at is a classic, I ended up travelling down the motorway for an hour and a two hour trip on Saturday.
Frankly, whoever I've been talking to about it (mainly women though) have treated me as a sort of travelling circus show with almost unison exlamations of 'ooh, I can't drive on motorways'
One man whose car I was viewing, at the news I'd driven two hours down the motorway had the audacity to point at his wife and say 'can you teach her how to do that' The Git!! 
To which the wife promptly launched into a heartfelt explanation as to why she couldn't possibly engage in such risky behaviour as tackling a motorway.
Having ranted said all of that though, I often catch myself thinking 'oh, I better ask a man to do that for me' Especially since my split from exp last christmas.
Then I sit down and think it through properly (i.e why does it have to be a man, what skills do you need, etc etc) So far on a lot of things I've come to the conclusion that there is absolutely no reason why I can't tackle it myself even if it is seen as a male thing do to/domaine etc.
Talk about using a power drill, teaching yourself how to inspect a car, driving on the motorway, changing the oil in your car etc in a group of women though more often than not over half of them will start the chorus of 'oh no, I couldn't possibly' and looking at me funny like I'm an alien species.
Not sure what the point of this is but in my own experience it often feels almost like I've been 'brainwashed' into believing I can't do something or simply must wait for a man to do it for me.
