Read the article again. She is talking about how stupid she is.
Probably the safest lane to travel in on Canadian divided highways is the leftmost lane of the express core. If a tire blows there, the only safe thing to do is to go to the nearest shoulder lane and not try to cross other lanes.
Perhaps she should have had a "send help" sign or a white towel to hang out a window or even better, a cell phone, but we can't fault that as many people travel without any of these.
She also recognizes the limits of her mechanical knowledge and so is prepared to accept expert advice.
Lack of knowledge is not the same thing as stupidity.
OTOH, the boyfriend put them both into a two hour wait in a Canadian prairie winter because he would not accept advice from a mechanic before setting out on the highway.
