[quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous]Automated emergency braking is, to my mind, the most important safety feature after a full complement of airbags and a strong passenger compartment.  It usually is paired with adaptive cruise control, using the same sensor to detect excessive closing speed and applying the brakes if the driver fails to do so.  [/quote]

Do you drive differently knowing these features are there?[/quote]

Not really.  I use adaptive cruise on highways, as it adjusts vehicle speed to traffic flow without me having to be constantly making tiny throttle adjustments myself.  That helps with minimizing fatigue, but I'm still steering and monitoring traffic for people changing lanes in front of me and so on.  Automated emergency braking does a couple of things:  it brakes for you if you're momentarily distracted or inattentive, which can happen no matter how good we think we are as drivers, or in situations as when you look over your shoulder before changing lanes and a car in front of you chooses that moment to slam on the brakes, and it applies the brakes with greater force than you might on your own - it's a common phenomenon that people tend to not brake hard enough in an emergency situation.  Most people rarely brake hard or practice emergency braking, and in an emergency they brake like they normally do.  With antilock brakes, it's possible to brake very hard indeed without losing control, but you have you really put your foot into it, which many people do not.  Automated emergency braking will apply the brakes forcefully if it detects an imminent crash, even if you're already applying some brake pressure short of maximum.

A bit off topic, but I figured that braking hard on the highway can save your front but increases the risk of the car behind you rear ending you, because everybody tailgates and not everyone has automated emergency braking[/quote]
