I tried the Adaptive Cruise and decided that I didn't like it, so I switched to the traditional cruise. However, Honda needs to tighten up the system responsiveness. If you are in among other cars and you set the cruise, be prepared to upset the drivers around you. This system will allow the speed of the vehicle to vary around 4mph. For a 2018 model year, I would have expected a more responsive brain monitoring the speed and incline changes. Set the speed to 65mph on level ground and as soon as you remove your foot from the accelerator, the car will slow to 62 and then start working its way back to 65. If this is intentional behavior because it is somehow more efficient, I'm willing to lose 1% efficiency to drive a consistent speed on cruise.
