I think your expectations are a bit high. Anytime you want to add security, you have to sacrifice convenience. Can't have both. It's like saying I want to have a safe that uses a fingerprint scanner, retina scan, and voice recognition to keep my money in it. The safe will be really secure, but you have to do all three steps every time you want to take money out.
Same analogy here. This is an Android security limitation, and not really anything Moto can do about it. As it is right now, you can't have notifications on the lockscreen with a security pin/pattern that shows portions of emails and texts without compromising privacy because anyone can see those previews, nor will voice activation be able to automatically unlock the lockscreen or any app that has a security lock. Just have to hope Google is working on giving more options that allow a various levels of security and privacy in Key Lime. You can use Tasker or Llama apps to set safe zones based on location data or networks to disable the lock screen when you want, but again you lose security to gain convenience in those safe zones.
