Cool, this book is now high on my wish list.

I think that developing a good working solution that drives the robot both
fast and precisely over the track, and still uses only 1 light sensor would
be the ideal solution. I´m still challenged on that.
Using only one light sensor would open the solution to virtually all RIS owners.
Obviously there are situations that would be impossible (or at least very
difficult) to deal with, like the 90+ degree bends. But it´s something we
could live with.

I agree. I don't like that idea too. Are we too purist ...?
