Jeep Uconnect Incorrect Software Upgrade

Recently, my Jeep Grand Cherokee notified me that there was a software upgrade to my Uconnect® system, which is the in-dashboard interface to the radio, climate control, navigation, etc.  To put it in their words, its "the feature-packed navigation, entertainment and communication system that lets drivers live their lives, connected."

There are a few obviously annoying points about how this upgrade worked...

1.  The upgrade was mandatory - Pressing the later button only postponed this pop-up warning until the next time I drove the vehicle.  So, my options were to press later every time I drove the car, forever, or let the update happen.
2. The update could not happen while you drove the car - Jeep expected me to sit in park and let my car idle for 15-20 minutes while the software updated. What a waste of fuel.  Why did the engine need to be on?  For what it's worth, I had the brilliant idea of leaving it parked while I went inside for 20 minutes, only I got distracted and let it run for hours before I came back.
3. The Update couldn't be interrupted -  When you start the update, another screen pops up warning you that if you stop it, you will have to start all-over.

A much smarter update protocol would have been if the update was downloaded to the car in the background, any time the car was on, and then the software update could be installed quickly after the download was completed.

I also read online, afterwards, that I could have downloaded the update from the Jeep website onto a flash drive and installed it manually.  It would have been nice if that option were mentioned in the pop-up instructions.
