And in mine, they should have been.IMHO, the front doors (driver/passenger) could have been manual.
As far as manual FWDs, I've given this some thought. The bulk isn't an issue; they could counterbalance them with struts of some sort. Our Odyssey tailgate is quite bulky but very easy to manage. With both, we need the option of manual and automatic. Not sure how they'd accomplish it, but I'd have preferred it as an option.
