I know a voice alert was added around 2024 for larger speed changes, but many roads especially state and county routes can vary widely and often going from 55 to 25 very quickly and then bumping slowly as you exit a town from 25 to 35 to 45 to 55. To avoid speed traps on entering a town a voice alert would be great for when the speed limits change by increments of 5 mph. Small town love to catch non-locals for speeding!!!
