There's a persistent assumption that handwriting fonts get a pass on spacing — that the organic irregularity of the letterforms will naturally absorb or disguise any gaps and collisions between characters. This assumption is wrong, and it leads to fonts that look unfinished rather than authentic. Bad kerning in a handwriting font doesn't read as natural variation. It reads as bad kerning. The eye is quite good at distinguishing between the two, even without conscious awareness.
