Reply To: davening S"E while driving

I believe that the author is R’ Avraham Ort. It is a sefer on the halachos that apply to a person who is delayed in traffic erev Shabbos.

Is this case specifically for erev shabbos/ yom tov where if he doesn’t daven while driving he will not make it to his destination before shabbos/ Yom Tov begins thus causing him to break the shabbos/ yom tov?

Yes. If he pulls over to daven, he won’t be able to have kavana because he is a rush to make it to his destination before Shabbos. (So he will rush through the tefilla.) It’s talking about a case where he believes that he won’t be endangering anyone. If he is able to pull over, or to daven once he arrives at his destination, then good – but in this case he can’t, and he can’t daven after he arrives because (according to some opinions, at least) Mincha must be completed before shkia. And this person will be driving until pretty much the latest time you are allowed to drive.
