Ok yes the speed limiter is useful in that once set at a speed you can't exceed that speed. I use the cruise control a lot even in town when the conditions are favourable. My C3 Aircross is Automatic and changes gear and the cruise stays engaged. So today I decided I'd use the limiter as there were speed cameras along the road. It worked well you release the accelerator and it slows down, put your foot down and will only go to the selected speed, in this case 30. Now the handbook says to override the limiter momentarily, push the accelerator to the floor. No matter how hard I pushed it wouldn't override. My 2017 C3 Flair automatic Hatchback wouldn't override either.
Anyone else able to override the limiter.
