Here's an idea. Everyone stop carpooling. Who is this really helping anyway. Do you really want to be cramped up in a car, with someone you really don't like anyway, just to save a little gas? Do you really trust them enough to pick you up on time? So many problems. One solution. STOP IT.
Ride wherever you are going in the comfort and style of your own ride. Even better if your personal car is an 18 wheeler, or a school bus. Imagine all the room you will have to spread out.
We can all dream.
