One nice touch I noticed in the Vauxhall Insignia rental car I was driving last week in the UK, was that the cruise control indicator had two colours, white when it was switched on, changing to green when the speed was set. In my Octy, I only see the (green) cruise control indicator, when it is switched on and the speed is set. There's been a number of times where I've forgotten to switch the cruise control off completely, could lead to a sticky situation if the 'res' is pressed accidentally... (I'm pretty sure the last speed setting is retained even after the ignition is switched off)
