Once upon a time,, Alot of cars had a mirror on the dashboard.

As for the current situation with your Dad, there is no way this is going to be easy (as you have alluded to with prior conversations w/dad)  but it's time he stopped driving.

You can emphsize your concern for his safety or your kids safety or the liability issues but somehow it is time for him to stop driving.  Find an alternate role for him to be and feel useful and important/needed.

Everyone "ages" differently as they grow older,, and a lot of times people who have spent a lifetime being useful/needed/important  don't age well when they can not do what they have done their entire lives.

I do not envy the position you are in. This is the begining of where the "children" start being the Adults and Parent's do not like it one little bit. Some are "ok" with it, many are not.
