Interesting article. I think it's good to teach kids they don't HAVE to share, but I personally also think it's important to encourage them to share their own stuff and think about others' feelings. I feel a little sorry for the kid in the article who wanted a turn on the red car toy and was ignored by the author and her son for 1.5 hours...that's not very considerate of others.
Ok. I can see the other perspectives on the car situation. I do think, though, that if it were my child and I saw another mother repeatedly tell him to get off of it, I would allow him to keep using it just to spite her. I know that sounds petty, but if he's not hurting anything there's no reason for another mother to try to change his behavior. I'd probably go up and have words with her. =Caenis= these are toddlers we're talking about here so you can't expect the child to point out to an adult that there are other cars available.
