I don't think I agree. In particular, if your car engine has a turbocharger, an extra 10 seconds of running before driving will hugely extend the life of the turbo (even more important is ten seconds idle at the end of the journey).
However, a few seconds pause and relaxation before driving off will make you a calmer, safer driver even if there is no turbo to look after.
OK, if you are driving a fire tender, it is different. But most people could simply get out of bed ten seconds earlier and have a less-stressed day.
