“Let’s say that passenger A’s usual fare would be $1, passenger B’s is $5 and passenger C’s is $9. If all three share a cab (and assuming A and B are allowed to hop out on the way to C’s destination, without incurring any special fees), the total bill would be $9 — rather than the $15 they’d have to pay, total, to ride alone.

Needless to say, you are right. And given our tech (read math) background we would approach it that way. Infact all the people I sent/asked did the same.
I am curious to know what is in WSJ, so I am hoping that someone comes across this post and gives me what is in WSJ (no, bugmenot didn't work). And am also hoping that some commenter gives me a different answer than the ones we know!

Ok, if you thought it is doing the job of alarm clock, you are wrong. Did I say loud ?, it […]
