This should be mandatory for truck IMO.

And all this rubbish is called progress, no doubt if fitted to some executive pen pushers car it would be, it might even impress small boys.This electronic junk de-skills the drivers job yet another level, and some wonder why they are still struggling to get £8 an hour basic.
It’s fitted to my Range and the BM but not the Aston !!! 
Driven a few mercs with this and its brilliant, should be mandatory equipment on lorries just like abs in my opinion. I was driving left hand drive and few times had cars dart in front and the ACC would brake before i had time to see and acknowledge it.
