Actually (this particular case at least) is a difieciency of TeX (not
supporting extensible math accents) and CM fonts (not having accent
arrows). The following example (processed by LuaTeX or XeTeX) looks
good, IMO:

\documentclass{article}
\usepackage{unicode-math}
\setmathfont{XITS Math}
\begin{document}

$\overrightarrow{AB}+\overrightarrow{BC}=\overrightarrow{AC}$

\end{document}
