Out of experience of others as I heard, if you do the adhkaar/duas regularly, and trued you best (not spent time lazy or in sins), then you will be rewarded/protected as usual, but we should complete/recite afterwards.
It is good to learn by heart the most important duas (and as the time passes), like for examole 10-20 from Momin ka hatyaar, so that we can recite (3x) while commuting etc.
It is good to pray 2 rakah nawafil for protection before leaving and after comming home (don't have time now to reference lesser known hadith).
If you spread the knowledge to others, you shall be rewarded for every nawafil of theirs too, inshaAllah.
It is good to give sadaqa (of cpurse after the must zakah) at the times of less time faculty.
Do not forget the dua for driving:

As you drive, if able to remain safe, make common dhikr like sunnah tahleel, estegfar, surah ikhlas or salawat (there are ahadith (+out of experience) regarding big numbers, so we can not limit them, not even a grandshaykh is in front of prophet saws).
