Nobody tells you it’s the last time you’ll all be in that car together. That’s why you pay attention now.

Last times almost never get announced. Things do not end, they thin out: someone moves, the schedule changes, and one ordinary afternoon turns out to have been the final one without anybody in the car knowing it. You only find out much later, and by then there is nothing to do with the information.

That is not a reason to be sad in advance, which would ruin the thing you are trying to keep. It is a reason to look up. Once this week, when you are with the people you are always with, take a proper look at the scene instead of your screen.
