Google promised an Assistant driving mode for phones would show up in mid-2019, but that clearly didn’t occur– over a year passed without any indication of it. It seems ready, though. XDA-Developers has found (by means of Android Police) that Google Assistant’s driving mode is at least partly allowed for Android users. The user interface has changed considerably from the I/O 2019 demonstration you see above, however the concept stays the same with large buttons and text that let you chat, message and play music while keeping your driving diversions to a minimum.The rollout appears to be server-side, and may be part of a test. It’s not connected to any particular versions of Google’s Maps or search apps, and likewise works on a variety of devices. Your gain access to may depend upon your account.
