Generally what I find is that they make a point of scattering the desirable features across packages in order to make you upgrade to the superset.
For eg. Honda Accord 2018 with all bells and whistles starts at $33.8K while the lowest one starts at $23.5K. There's a good chance that a 40% increase over the base price will put that car out of the budget of a lot of people.
From their perspective it should be setup like cable subscriptions. So, different segments buy the same package for different reasons.
You are standing in the maze of twisty little options, all of which suck.
Acura TLX has the option for automatic cruse control, lane followings, and automatic breaking. It has a second option for blind spot detection and several other things. Want both? They have a third option that includes both plus some other stuff but it costs even more.
I mean why blind spot detection as part of the safty package when you can charge 3x as much to include it.
The things that they make you choose between are ridiculous. It's like they put all the features on lottery balls, spin the bucket and pick 6 at random for each package and that's what you get. At least make the feature packages make sense
