In its now second annual hardware event, Amazon today announced Echo Auto, an in-car accessory that allows you to integrate Alexa into your car.

There are a couple of ways customers can already access Alexa in the car — you could download an Alexa app, buy accessories or even a Moto Mod, or drive cars with the software built in. But the Echo Auto makes it far easier to integrate Alexa into any car, regardless of whether your automaker included it or not.
