Motorola Assist, the contextually aware app that lets you set triggers and actions for a wide variety of tasks, is smart enough to determine when you're driving, sleeping, in a meeting or in other situations. In that first scenario, however, the app was only able to read texts out loud to you as you drove, leaving you without a way to respond aside from pulling over and doing it manually. The latest update to the app fixes that, as it promises to let you reply to incoming messages using your vocal cords. Additionally, Assist can also launch your music app of choice as soon as you begin driving. Assist is available on the Moto X and the trio of Verizon's latest Droid devices, so text-happy drivers should check it out post-haste.
