When I'm stuck in slow-moving traffic, I'm not interested in the distance to the next speed camera. It would be sensible if this would only be announced (I ride a motorbike with audio navigation via earphones) if I'm travelling too fast. It's particularly annoying when moving at a slow speed along a congested M25 around London where there's a speed camera every half a mile and any chance of travelling at a speed even close to the speed limit is remote but the warnings come every couple of minutes and just increase the stress with useless information blasting (I need the volume at full to hear it above the wind noise at normal speeds) into my ears.
