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).
My experience with those was that they proved formulaic and repetitive after a time, but the first few were good. They did have problems with shallow characterisations, though, at least to me.
