Too true...I got pooh pooed in Jimmy Olson's other thread for suggesting that automation leads to inattentive drivers, and an over-reaction when they DO wake up...

We found that when drivers were not in physical control of the vehicle and had an artificially reduced situation awareness during automated driving, their response to an impending collision after an uncertainty message in critical events involved greater maximum deceleration and higher maximum lateral accelerations, whilst they also maintained a shorter headway with the lead vehicle, when results were compared to manual driving performance. The response profile of drivers to a potential collision scenario wa s, therefore, less controlled and more aggressive immediately after the transition. Given that the uncertainty alarm was not a take-over-request but rather a request to monitor the system and intervene if they deemed necessary, it is difficult to accurately assess response time to an event. Nevertheless, taken together these differences suggest that following automation, drivers have a diminished capacity to respond as they would under normal manual control.

The study, which measured the effects of cruise control and speed-limiting devices on driver vigilance and behaviour, was released by the French based VINCI Autoroutes Foundation for Responsible Driving.
“The less work the driver has to do, the less alert he will be behind the wheel,” said Bernadette Moreau, General Delegate of the Foundation, which researches hazardous driving behaviours. “It is widely known that these tools are very effective to maintain safe speeds, but call for user savviness and awareness” to be safe.
Driver attentiveness is a hot-button issue worldwide, with various governments pondering legislation that would supplement bans on texting while driving with strict limits, or outright bans, on using internet-enabled features while their vehicle is in motion.
The study indicated that by automating control of the vehicle, there is a decline in drivers’ attention and control, which reduces their ability to respond to hazards.
For example, when cruise control and speed limiters were used, drivers showed reduced ability to merge into traffic due to greater difficulty in modulating vehicle speed. The aids also caused drivers to remain in the overtaking lane for longer periods of time and to move back into the slow lane less often. Drivers straightened their vehicles less often when using these devices, and had substantially slower reaction times, especially in emergencies.
These behaviours grew more pronounced with the duration of travel, especially when using cruise control. Generally, the reduction of alertness and control was greater when using cruise control than with speed limiters, the researchers said.
The research was conducted by the Centre d'Investigations N

When I need to change speed to change lane I disengage cruise control.
Th studies in your linked are all bunks, they do not reflect real life condition because they were all simulated.
As I said in another post, you can extrapolate from a study of few person in a lab to real world condition.
Speed control causes more accidents and deaths ? When speed was reduced to 55 MPH in 1974 the number of death reduced by 17%.
