When we're rerouted to avoid congestion it would really be helpful to get a brief reason.
When Waze reroutes us to avoid congestion, it would be very helpful if it could briefly announce "rerouting due to congestion" or words to that effect so we'll know that the apparently strange new route isn't the result of an inadvertent electronic "hiccup."

Thank you for your valuable feedback. We're pleased to confirm that this suggestion is planned and we appreciate your input as we continue to enhance our product.

The Highway was closed due to an accident. It just rerouted me but I had no idea why. If there is a deviation in the route it should announce it as soon as it is known. This would allow me to review optional routes from backed up traffic, or an accident.
