It's easier to teardrop a body with one wheel on one end.
Maybe tires are not as sensitive to scrub as I imagine, but one wheel should not suffer side scrub by itself from imperfect alignment/track changes through suspension travel.
One spring/damper assy ought to be lighter than two.
Trikes aren't mainstream because they are more load sensitive. The lowest common denominator users out there can't be trusted with that. Add wheel #4, gain lots of safety margin.
