It also comes down to the weight and the torque of the engine as well ( for towing ), personally I`m not too fussed about height but for some its a bit more comfortable for sitting and getting out off. I never bought the Honda initially for its 4x4 capabilities albeit its not even a proper 4x4. However the extra room that comes with it was good and at the time I also needed a full child seat and boosters for the three kids. That was 7 years ago so they are all gone but two teenagers and a 9yr old now means there alot out there with the room. Horses for courses, personally I may keep the Honda but replace the Picasso.
Also cushion/cinema ??? I too fail too see the relation to this, its what she is comfortable with ???
As with a cinema seat, if you sit higher up to see over the person in front of you, you then (selfishly) block the view of the one behind you.
Similarly, the car arms race is there in both the height of the car and the weight of the car. Your typical Range Rover driver seems to rather like the idea of having a heavy car in the (mistaken) idea that it is safer, while of course overlooking the extra damage and longer stopping distance of his heavier car and its impact (literally) on others. The extra height then blocks the view for other road users and makes it less safe for them.
So on both points the car choice has some negative aspects for those around you , thus the analogy with the cinema seat.
