Volvo Cars unveils its new City Safety system, which is designed to help drivers avoid or minimize damage from low-speed rear-impact collisions. If the system senses that a collision is imminent, the car will brake automatically through hydraulic pump activation. Depending on the speed of the two vehicles, the system can either help reduce speed as much as possible before the impact or stop the collision entirely. The City Safety System will be on the market within two years.

jileras, u got it right. they have to make it last minute but not the last to stop the car as otherwise this system will interrup the driver for braking during needed.
"I've noticed this car will not brake until the last second"
That is the idea. We do not wish to have a system that will be a nonsense, meaning it will constantly activates if one gets just a little to close to the target vehicle. The consumer will then deactivate the CSS, thus defeating the purpose of having it in the car. When a collision is imminent, and only at that point, CSS will if possible, prevent or minimize the collision.
Basically what Mercedes has already done but on a much smaller budget. I've noticed this car will not brake until the last second which has is a disadvantage which stopping suddenly might lurch the occupiers forward. Also there is more chance of it hitting the car. However, this DOES seem unlikely if you are only dealing with speeds 30 mph or less...
I wish the car that rear-ended me had one of those systems. :(
