At the moment they are driver assist systems but as we the driving public become "trained" to use them , or stop turning them off , then they will become permanently on systems for the new generation of drivers, but most likely with many legal warnings in the handbook saying the manufacturers will not be liable for any incidents that may occur due to their operation or non-operation. I think there could be a bright future for 16 year olds wishing to take up a position in the legal profession , especially ambulance chasers!
