Anyone know if the 2017 Volt uses camera or radar if you have DC1 and DC2 but not ACC?

On the models that have ACC does it use radar or camera? If ACC does use radar does it help detect vehicles in fog better?

I have DC1 and DC2 but not ACC. Since it looks like retrofit for ACC is either not possible or really complicated, was thinking of getting a Drive Safe radar system to detect vehicles in front better especially for foggy situations if DC1 and DC2 doesn't use radar.

I have heard of other models being successfully retrofitted with ACC like below. Just wonder if this will ever be possible on Volt....

As far as I know, only cars with ACC have forward looking radar. That would mean FCA on non-ACC cars must be camera based. I suspect it is camera based on ACC cars as well, but I don't know that for certain. Automotive radar typically has problems correctly identifying stopped cars to begin with.

If the fog is so bad that you and the camera can't see far enough to drive safely, then maybe you shouldn't be driving in those conditions at all. Radar probably isn't reliable enough to make those conditions safe.

You don't know the environment in some regions.

You can leave home in sunny conditions, encounter a patch of light fog, and suddenly be enveloped in dense fog.

This typically happens in the morning, and regularly not showing up to work because of the possibility of fog isn't a viable lifestyle for most people.
