It doesn't save them money unless they have to actually pay for ALL the damages. Let me explain to you how big companies do the maths.
This is oversimplified, but explains a lot:
1) Plan for safety measures: x millions dollars.
2) Damages to materials when an accident occur: y1 millions dollars.
3) Lawsuits or out-of-courts settlements for victims' families: y2 millions dollars.
4) Ecological damages: ???
If x>y1+y2 when adjusted to the frequency of the accidents, then it is not cost-efficient to build safety measures, because it will cost less to simply pay when an accident occur. However, if point 4 is made to make them cough up billions of dollars as it should, then it becomes vastly more cost-efficient to have viable safety measures. But because point 4 is very difficult to enforce, and even to estimate in money, then usually only points 2 and 3 enter in the computations.
