Was checking out the 2018 ordering guide for the MY18 CT6, hoping to see supercruise which didn't appear to be listed but saw this:

" Full-Speed Range Adaptive Cruise Control switchable to Regular Cruise Control (within [KSG] Adaptive Cruise Control; included in [UGN] Driver Assist Package)
Full-Speed Range Adaptive Cruise Control resume and engagement from stop"

Both are great improvements and unrelated to supercruise, the second being great for traffic...

I understand the advantage of the second but can't think of a situation when you'd want regular cruise control rather than adaptive. Regular is simply a not working version of ACC. LOL

Some folks want the blind cruise control for when ACC won't work because of weather or system issues. A few folks posted long rants on TMC about how annoying it was that Tesla didn't give it to them.

Before this I only knew of one car that allowed both types of Cruise - the Infiniti Q50.

I believe that the reason most manufacturers don't allow it is the potential for confusion - inevitably, someone will eventually manage to engage the blind cruise while thinking that they engaged ACC, and they won't find out about it until they get really close to or hit another car.

At that point they'll probably blame the manufacturer, claiming the car crashed into something while in ACC.

Didn't think about ACC not working since I've never experienced this. Agree that having both ACC and regular cruise is potentially confusing. Also agree that if someone gets confused about which one is being used the manufacturer will be blamed.

How much driving have you done under ACC? I think most of them have foibles. I've read of a number of systems being taken out by snow buildup on the nose of the car, some folks have said rain blocks some systems.

My Tesla dislikes the southbound tunnels in Baltimore for some reason - the northbound ones are fine, but the southbound ones both produce "reduced forward radar visibility" that knocks out TACC and AP for the second half of the tunnel and a few minutes after exiting.

Standard cruise if you have adaptive is silly. Use the Up and Down arrows if you like. Or drive the car. All ACC does is stop you from hitting the car in front of you. Nothing else. If you really need to ram them, just hit OFF and punch it.

Something is fishy with that. 335HP V6 the top engine for the Platinum? Really?

A good number of miles over 2+ years. Never had a weather related problem. However, keep in mind that even rainy weather is unusual for me, so that may explain my lack of experience.

The only problem I've encountered when using ACC is the car not recognizing a car ahead on a very twisty road. But regular cruise control wouldn't help in this situation.

I think the most expensive engine is a twin turbo V6 that produces 404HP. At that point the CT6 is up around $87K, which is why I think the hybrid is a compelling offering if you're interested in a big sedan like this.

saghost explained why, for some of us where weather related problems cause the ACC to be disabled, it would be nice to have at least a CC fallback option, to use when safe (wx and traffic conditions). Those in better weather areas might not experience the ACC inoperative condition very often.
