Rolling In The Rain?

Right now a bunch of bleary-eyed robotics geeks are lined up for a group photo, but they can be forgiven for looking over their shoulders at the same time.
A band of rain is poised to sweep northward through through the Detroit area. That will certainly wipe out confusing shadows, but it might dilute the lane markers and leave robots wandering (wondering?) off in all directions. The big fear is the rain will arrive just as JoeMegatron and the Miners are qualifying for today’s finals, but so far there’s no indication of lightning in these clouds.
And that would be good for those delicate neural circuit boards that “control” (if you want to use the term) these contraptions.
Gonna be interesting. And wet.
