Xeler8ing: As usual, good detailed and valuable input. Thank you! I think you've fully explained this now and, unfortunately, the Australian version is my dream but not yet to be.
Just so you know, for ME the difference between gas pedal or resume button input is literally the ENTIRE thing I care about. Since your magic version isn't available here in the U.S., what matters to me is not being stuck in an hour-long stop and go traffic jam and having to move my foot brake =>pedal=>brake=>pedal over and over and over which, because I'm disabled, is painful and exhausting. Being able to instead only use my finger to pull the resume switch and let the car stop on its own ... then pull the resume switch and it stops and pull the resume switch ... is a HUGE difference to me and worth every penny.
My desire was/is to make sure the 2017 Mazda 6 has THIS "finger-driven" version of stop and go cruise and according to at least one helpful forum member it does NOT. This is contrary to what a salesman/driver at my local Mazda dealer SAYS his does. So I need him to put his car where his mouth is and PROVE it ... or I need to either wait for the 2018 or rebuy my 2015 Hyundai Genesis when it goes off lease.
Thanks for the SO helpful input! Alley
