Article doesn’t say she steered it. You say the driver was dragged by the mirror but to me it looks like the driver maybe pushed it away just enough to enter the driveway rather than go over the gutter.
You can see it veers suddenly when it reaches the driveway. The right wheel reaches it first so that would have made it veer right.
And if it did hit the gutter instead it would have slowed, maybe even stopping by the time the rear wheels hit.
Uhhh
“It was heading near the petrol tank and no one was doing anything so I jumped up, got into action and steered it away.”
Well… no mention except for that part. 😬
