Whatever is offered as a replacement for the current Defender, a lot of the features will be there to meet safety requirements and a lot will be there to meet emissions standards or some other regulations. Those changes are obviously not negotiable.
The changes I would not like to see are the frivolous ones that are merely dictated by fashion. For example if the stylish outside shape impacted on the usable interior space, I would consider that a retrograde step.
Most boxes, containers and fridges are basically rectangular. You can fit more of them into a rectangular interior than into a curved one with protruding bumps.
I also see no need for things like electric windows, electric seat adjustment, auto sensing windscreen wipers. If you can't wind up your windows and adjust your seat manually and you can't tell if it is raining, then perhaps you shouldn't be driving.
I can see the sense of changes that make a vehicle safer or more efficient, even in a Defender. I can't see the need for replacing a simple, reliable, effective manual operation with a push button version.
