Not so! Although I absolutely CAN change a tire, put on chains and loosen up the linkage with a tire iron, I haven't actually had to do any of those things for decades.
I'm no supermodel but every time I've had a roadside emergency, by the time I formed a plan of action, some dear guy has already pulled over and is busily testing his portable impact wrench.
Now, I've never had to accept any of these offers of help at night or in secluded places so I don't know about that angle but I've never had trouble getting help during the day.
Maybe quite a few guys really ARE nice! That's been my experience, anyway.
I actually knew a couple with a daughter who's name was Ginger Snapp.
