That said, I can see a future where most "full-line" automakers have 1 or 2 economy car models (e.g. Toyota Yaris and Corolla), a couple of crossover SUVs to occupy the mid-range, and a pickup / full-size SUV.
I don't see Toyota ridding itself of the Camry for now, or BMW trashing its 5-series.
People who have reached a certain age probably find getting into and out of crossover SUVs easier because the ride height doesn't require as much bending and lifting oneself.
In my case, a Honda CR-V is much easier to use than a Mazda 3.
