Wow, I bet the engineers who design cars would never think of that. Good thing some rando on the internet figured out something that a bunch of PhDs and engineers would have missed.
That doesn't look like lens flare to me. Looks like a smudged lens--especially in that third photo. Judging by the shadows the sun is behind the drone at 7 or 8 o'clock, so I don't see how you could get lens flare with that geometry.
New pilot, no problems yet.
