Honda’s sensing system will read shadows from bridges as obstructions in the road that it needs to brake for. It’s easy enough to accelerate out of the slowdown, but I was surprised to find that there is apparently no radar check to see if the obstruction is real.
My current vehicle doesn’t have that issue, so either the programming has been improved or the vendor for the sensing systems is a different one (different vehicle make, so it’s entirely possible).
This is how I did it, using my Mac laptop. You can’t do it with the phone app, but a Mac or Windows computer can.
