What should I say or do, if anything at all, to my neighbor who I came very close to running over this morning?

Long story short, crazy holiday season and I’ve been running crazy and stressed out. I live in a quiet, fairly close knit neighborhood and on a Sunday morning, no cars around and no pedestrians. This morning, I got into the car and backed out of the driveway. I heard someone yelling “whoa whoa whoa!” I heard some noise or commotion, too. I pulled back into the driveway and I saw my neighbor (he lives about 5 houses away) walking away with his dog. I called after him twice, that I was sorry. I then said “Did I hit you?” He just put his hand up as he walked away. I imagine he was so upset he didn’t want to talk about it.

I am wondering what, if anything, I should do. I sometimes see him at the school bus stop when he accompanies his daughter. Should I bring it up to him and apologize again? Should I not say anything?

The two friends I saw today both told me to let it go.
