Cz is taking good care of his little brother, Aj, and teaching him the ins and outs of safe jeeping. Aj sits safely on the floor (so he doesn't fall out at those high speeds), and Cz is looking everywhere except where he's going.

You can also see the look on Aj's face; almost as if to say "what the heck, mom?" As time goes on and learns, Cz spends a bit more time looking where he's going, (not always), and Aj get more comfortable and eventually starts sitting in the seat instead of on the floor.

I suppose it's good that Aj gets some seat time with his brother, err, well, floor time as the case may be. Being a good passenger is always nice for the driver. It also helps to promote better learning. Being able to learn from someone else's mistakes has always benefited me.
