This could be said about any tagging. A road might be one-way but the mapper might have forgotten to add the oneway tag, or it might be bus only or only accessable at certain times of the day, and the mapper simply failed to add the tag.. this doesnt excuse you as the driver in control of the vehicle from following the relevant laws on-the-ground. Anyone who trusts their GPS's speed-guidance above and beyond the posted speed limit signs, has no-one to blame but themselves. I see the maxspeed tag being useful as a guide to your speed limit, and also useful in calculating accurate ETAs, but I dont think it should be depended upon as a certainty. If the GPS says the speed limit is 80 and there are 40km/hr roadworks in-place, its the drivers responsibility to follow the posted limit, not the limit being suggested by their GPS.
