a tip that I have to speed the update process a bit is that the first 5 updates you can install one over the other just fine, it is around the sixth or seventh (it is the first update to have something like 2GB) that Polyphony made a in game utility to compress downloaded data and that it is what causes issues if you "binge" a lot of updates in succession. You dont need to disconnect of the network to stop the console to install everything one over the other, just press Circle, it will open the game, the preparation process will start, it will decompress the files and when finished, you quit the game and it will ask to download the next update... I know this is very annoying, but I understand why they did this, the patch files were starting to get pretty big and if you were playing when the game was current, it would be uncommon to install around 22 updates in succession.
