Query: Hard to use for younger kids; some features didn't work

I bought this thinking it would be a good choice for our young son. In particular, the package lists a special mode that will "steer the car" for a younger driver. After buying the product, it took me about 5 minutes to find this feature in the (confusing) documentation, only to find that it apparently doesn't work.
