[Q] Change screenlock when car docked

[bkenobi69]

I'm running a Droid4 with ICS and use it with the Motorola car dock. When I'm using the phone on its own, I like having the slide screen lock so I can immediately go to phone, text etc. However, when I'm using the phone in the car dock, I have no use for the screen lock. I generally turn the screen off when driving unless I want to make a call or switch audio tracks. This requires paying attention to the phone for a second or so to make sure I'm sliding the right location which feels unsafe. I'd like to keep the screen lock on normally and not have to manually switch it to none when docked. Is this a built in capability that I'm missing somehow? I didn't see a way to do this with smart actions (which I already use for a couple tasks). Any thoughts?
