From a cold start, there are a lot of components that need to "spool up" so to speak. The car is designed to keep a lot of the electronics active to minimize this spool up time when you are making short/quick trips. If you have the second gen iDrive you can really notice that it takes a good 30-45 seconds to display the intial map screen when you cold start but only about 15 seconds from a warm start when the car is awake. Same is true for the fuel pump, etc. The engineers designed it so as long as you stop and start the car within 16 minutes (I believe that is the snooze time), everything stays awake. Between 16-30 minutes more stuff goes to sleep and after an hour everything goes to sleep.
