The chiming gets more insistant the longer you leave it (we have several long straight empty motorways here in France).
I think the system comes into its own in stop start motorway jams which I happily hardly ever encounter but I appreciate every aid going to assist me in day to day driving as I am after all in charge of a lethal machine and human. We all make mistakes and anything that helps me not too is welcome.
Can anyone else confirm the warning chime in the e has been removed? That would seem a retrograde step to me.
