HI
Updated answer,
Breaks are important, however the breaks can fail. The most "important safety feature in a car" is anything that stops the driver from injury, or ensures he will survive an accident. Air bags, a roll cage and safety cell for driver and passenger's are the most important. Volvo have these features as standard in there vehicles.
The brakes.
Safety belt.
In my opinion, the seatbelt. Without it, a casualty rate due to car accidents would increase dramatically. Seatbelts are an extremely important safety feature in a car. Buckle up!
An awake, observant, and well trained driver.
The most important feature is dependability. If the car is not dependable you will soon regret the purchase. If you are talking about safety features then the crash test rating of the car is the most important. If you are talking about other features then a back up camera is what I love the most about my 2013 Honda Accord.
A competent driver is the best safety feature in any vehicle.

The most important feature is the ability to start cars from a distance. It is very useful, as one can turn on the heater from a distance, when it is cold out.
