Just a little more detail...

Since the armatures of MG1 and MG2 hold the PM magnets and no copper wires like a regular motor it's not the centrifugal forces that are the main worry. Who knows what the maximum rpm is. I've had my NHW11 up to 60mph with no problem.

What I don't understand is that if it was so bad to leave the engine in neutral ICE off over 42 then why didn't Toyota explicitly warn against it or install a warning/error/failsafe?

Where does the prohibition come from?
