The major selling point of Android Auto is that it brings smartphone-like apps and services to your vehicle. Google Maps, access to music and weather updates are now taken for granted, but it's remained a mystery over why one of Android's most useful hands-free commands -- "OK Google" -- has taken so long to come to the infotainment software. Luckily, the search giant has finally recognized the need for the feature and is in the process of rolling it out, albeit at a slow pace. The feature was first spotted by Reddit user neo5468, who noticed that the latest versions of the Android Search and Auto apps enabled a new toggle for OK Google commands while driving. However, even if you have the new updates installed, Google appears to be limiting the expansion on an per account basis, so you may need to wait your turn.
