Since I got the Moto X I haven't paid much attention to the drive mode as I don't receive a ton of texts. But today I received a couple while driving and #1: it didn't read the message and #2: It doesn't appear that it replied that I was driving...should the reply show up in the messaging app? I am using Handcent, but it is not set as the default app. I'm not into the hassle of uninstalling handcent just to check on this, but anybody else with this type of experience? Not sure if the drive mode is doing what it is supposed to...
