Peace

Coming back from Dundee, a warning sign came up on the car dashboard informing the driver (me) that I should take a break.  I have no idea how the had determined that - perhaps we were approaching a cafe.  I didn't sleep particularly well but didn't feel the need for a break.  I drove on.  Some time later, we passed a motorway sign telling drivers that "Tiredness Can Kill" - take a break.  At the same time, the message on the dashboard came up again - take a break.  A co-incident or what?
