...get out of the saddle to really push?

I've pretty much all but stopped getting out of the saddle unless it's a pretty hefty hill and/or I really want to maintain my speed or push like a crazy MF.

I realised this morning while at a red light that I still manage to take off fairly quickly when I have to, but rarely ever lean forward/stand up to do so. More often than not, I'm out of the saddle to get slightly lower in a draft or bad wind. It's obvious that when I stand on the roadie, I'm even a little wobbly because I'm just not used to it especially on that bike.
