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.
Quite often, those complaining about they annoying beeps and warnings need it the most - they fail to realise they are half in a bike lane, that there is someone in the blind spot, and they aren’t using their indicators to change lanes.
This research was using older cars, between 5-7 years old atleast. It can only get better.
