At least they're advertising it. I'm not sure it will help the road toll much, I suspect it's more affected by the idiots who will ignore this, drive drunk, etc, than regular people going fast, but if it actually saves lives I support it. I hope they still use a bit of discretion, such as at the bottom of hills, but even in the auto with cruise control on you can use gears and brakes to limit your speed.

We're going to get cars going even further below the limit now. Most cars speedometers say they're going faster than they really are - when ours says we're doing 100kph we're actually doing about 93. According to multiple GPS units we have to do an indicated 108kph to be doing an actual 100kph.
