Yeah, I have quite a number of shots taken from the car - moving or stopped at traffic lights, etc.
Many times, we don't get to stop and get out while travelling, or we'd never get anywhere... so next best is catch as many as I can, then we'll see what came out good.... :)
These, I normally mention they were "Caught-on-the-move" and I like to leave part of the window visible, as you noticed...
