Dr. Declan Bedford:

It was quite interesting that I had this feature in the car for a number of years and it never said anything to me. One night I was coming back from Galway at about 1 a.m. I live in Navan and was an hour and a half into the journey when the car told me I was looking tired and to stop. It worked. The national road strategy proposes that by 2050 there be zero deaths and injuries. All of that technology will have to be involved. The main message about driving while tired is there is no way of stopping it except for getting out of the car, having a ten-minute nap, getting some fresh air or having a cup of coffee.
