Well, I would say it SHOULD bring overall prices down. If the cost to build the top of the line model comes down to say the same as the mid-range model AND more people are say buying up. It means that competition would push overall prices down.
But of course not, it benefits the companies most, and given the choice of lower prices or more profit, they'll choose the profit every time.
If they go subscription only (because recurring revenue is the current business buzzword, so of course they will go subscription only) then overall cost for the life of the car will definitely be higher yet "feel" more affordable.
