I meant to add that the friction is in the tyres, not the lego assembly.
They are too wide and the rubber causes too much friction.
If you only turn the front set of the 3 axles, then it causes the other 2
axles to skid around the corner.
But because of that massive rubber on the pp wheels, they dont skid, and the
vehicle just carries on almost in a straight line.
So you have to have the back axle steering too, or the middle axle (as in
that mobile crane in the technic ideas book) Or even all 3!
