My guess is that it won't cater for either of those cases. It seems unlikely that Google would program their cars to break the speed limit just to save you a few minutes (speeding probably saves you a lot less time than you think it does). Also, I cannot see why anyone would deliberately and continuously take advantage of the automatic safety mechanisms on self-driving cars such that the problem would be common enough that it would cause a passenger any irritation.
