By chance, don't you know why we cannot have electric wheelchair for everyone who needs it? Manual wheelchair seems to be not very convenient and to require lot of effort to use it.
Motorized wheelchairs are not a good fit for everyone. They are much bigger, heavier, harder to transport (you need a van), and even with a clutch to allow emergency non-motorized use, because of their design and weight, they can't be really used without a motor, so you're f*ked if the battery runs out.
They're good for some uses, for some folks, but are not a solution for all.
Newer battery tech is helping improve the “compactness” of motorized chairs. We have a “fold and go” (https://www.foldandgowheelchairs.com/) which can fit in a car trunk (though still want a full size sedan or bigger if you plan on putting anything else in there) and at 60lbs is only about 50% heavier than some of the heavy “standard” chairs out there. Still not something you’re going to move well on your own without an able bodied assistant or some specialized equipment, but compared to older motorized chairs it’s a huge improvement
