A study from the US's Insurance Institute for Highway Safety has looked at whether ADAS actually works.
And they've found that mostly they have resulted in no reduction in crashes. Blind spot monitors. Lane keeping assistance. Their potential to reduces crashes doesn't translate into any actual reduction.
The exception is forward collision warning with automatic emergency braking which produced an 8-13% reduction in crashes, depending on the model.
So the safety regulators punish vehicle manufacturers with poor vehicle safety ratings unless they fit the various ADAS devices as standard, meaning car buyers have to pay for them, and they don't work. They push up the price of cars with bringing down the subsequent cost of crashes and insurance.
Why does that not surprise me?
