it was a good thing I'd taken a registered vehicle, because you never knew, did you? Though I couldn't see any special registration number of anything, and I didn't think to make a note of his licence plate—and it wouldn't have made any difference, I don't suppose.

拉她去酒店的司机告诉她最好乘有牌照的车（即使在世界上很安全的少数几个城市）你也不知道会发生什么。 虽然我没看见司机有任何特殊的牌照，我也不想记住他的牌照--我认为那（记住车牌）不会有什么不一样

然而：When the woman said I don't suppose, she meant that she didn't believe that it wouldn't have made any difference whether she had made a note of the licence plate or not.

这句话的意思好像是：我不相信（记和不记车牌）不会有什么不一样，意思是：我相信（记和不记车牌）会不一样

我理解这段独白的意思（不知道是否正确）：讲述她每次度假去一个新地方的酒店都要付几倍的乘车费。
