When I look at the Location History Google has on me for my time at work it's pretty accurate, which is unsurprising since it is in a single fixed location and involves a fusion of not just GPS, but also Accelerometer and WiFi data. It's entirely possible that is less accurate for others, but it's a source of data that many people in this situation should already have, so you can use it for those for whom it is more accurate, and ignore it for others.
