During departure, I'm busy getting cleaned up and configured for the enroute climb, and I don't have a really great view of other traffic, especially at our climb speeds which may be closer to 300 knots, even below 10,000 (minimum safe speed allows higher than 250). I may be on a vector, and I may pass in and out of controlled airspace during that climb.
SNS3Guppy,
Under what permission do you do that?
