Its alright, but your not getting any progress for at least three minutes of that idle time... Its better to just start the car up and go... It says in my owners manual at least to Not idle for extended periods of time, and to me, starting it up and letting it sit for almost ten minutes, that extended, it isn't a diesel. I'd say start it up, wait a couple minutes, get in the car and go, by time you are at the exit of your neighborhood you can turn the heat on full blast and it will warm you up quickly.
Also, if you haven't done already, switch to a higher quality engine oil so you don't risk damaging during cold starts. Lower quality oils don't protect in below freezing temps as well as a quality synthetic does.
