I find some of the comments in this thread rather astounding, selfish and distasteful.
Safety features should be regarded as good things, intended to protect you, your passengers, pedestrians and other road users. None us as drivers as infallible, and we all make mistakes as do other road users. I would much accept the cost of the added technology - and associated repairs where needed - knowing that I may injure someone rather than kill them... or that my kids may end up with relatively minor injuries rather than become bed ridden after being hit by a car.
Some of the many reasons I drive Lexus cars are their safety features and records. And I am glad that airbags, pop up hoods, ABS, TCS and the like are becoming the norm.
If money is your only incentive and you are only concerned by how much it is going to cost to repair your car after a collision, be it with a car, pedestrian or other), maybe a modern car such as a Lexus is not for you and you should go for a 70s Skoda.
An expensive car will lead to expensive bills. Deal with it... or buy something else.
Rant over.
