I think we're sort of saying the same thing. I agree it can be helpful. But the key thing is how you use the 'freed-up capacity'. My worry is that some drivers will behave differently from you. Maybe taking a little longer when interacting with the Sensus screen... maybe taking a little longer when re-programming the satnav etc. I'm not arguing that we dispense with these assistance systems - just suggesting that more thought is needed about how we maximise their benefits. I'm with you about not placing any reliance on their performance. But don't get me started about the poor quality of the alert you get when PA has disconnected...
