There was no tone when I opened the door, not that I heard anyway (it was a 2017 Citroen C4). The dashboard may have stayed lit but as it was a hire car I had no idea what the normal behaviour should have been. I had two passengers who also did not notice anything out of the ordinary when we left the car. A colleague had the same thing happen in a C4 but he was still in the car when the engine restarted.

This happened to me with a hire car. I parked the car and pressed the button to stop the engine. The engine cut out so I got out of the car, locking the vehicle with the remote as I walked away. After some time I was contacted by the security team of the company I was visiting to tell me the engine was running on my vehicle. The auto engine off had kicked in as i pressed the engine stop button, but because the engine had stopped I didn't hold the button for long enough to actually switch the engine off. When I locked the car the turn indicators flashed with a non-standard pattern to warn that the lock had failed (because the engine was not off) but because it was a hire car I did not recognise it. When I drove the car home the same thing happened at the end of the journey but this time I was expecting it and switched the car off properly.

I don't think it's a zero sum game and I'm pretty sure other factors are involved e.g. stress, alcohol intake, volume of exercise, etc). I do know that my perceived quality of life is improved when I'm getting plenty of sleep, and for me that requires about eight hours.

As I wrote in my initial comment the occasional disturbed night is not a big problem when I'm well rested. Under those circumstances I never feel the need to get extra sleep to compensate for the lost hours.

Over the years I've found that I definitely need 8 hours sleep but didn't often get it. I would normally manage about 6-7 hours and would soon build up a deficit. This had a definite impact on my well being and performance at work. Recently I've started using a timer instead of an alarm clock to ensure that I always get eight hours. If I go to bed later I get up later. On the rare occasions that I go to bed substantially later (e.g. attending a concert) and so can't allow eight hours, I still cope well because I'm already well rested. Ditto for when my young son wakes in the night - previously this would have killed me.

I know this isn't viable for everyone but my employer allows flexible working hours.

Renders perfectly in IE8.
