No doubt its helpful…
You still missed my point, its not just the retards who can’t look before they merge, but good drivers who may become spoiled by an AID such as the blind spot warning, and become lazy stop looking. What if it stopped working one day, the never heard/saw a warning and merged into someone?
Now Im not saying this is going to happen on a massive scale, nor am I saying it may happen at all, I bet most people who own cars with these type of features will be trading them in and getting new ones before they even have a chance of going bad, and as said earlier I’m sure the dash will light up like x-mas if any sensor goes bad.
More or less just how I feel it will make people too dependent on the car itself to do all the work rather than there own ability to drive safely.
