I posted this same question 5 months ago, but will be buying a new car next week and still can't make my mind up.

I am getting a Mazda CX3; I chose that because I really need the blind spot monitoring.
I don't need collision avoidance or lane departure warning, but since I will be driving this car for the foreseeable future, I want to get it right.

They would cost me $5,000 more. (yes, that $5,000 also gets me a sun roof, navigation, pandora etc. etc; but none of it has any value to me.)
The salesman I spoke to says that collision avoidance is only useful on cruise control (which I don't use) and lane departure warning are generally annoying.
He recommended I save my money.

That was your general consensus 5 months ago, but I just can't make up my mine.

Any strong opinions? (yes, I do own a sawstop; why do you ask?)
