Because there's a only slightly smaller standard track gauge that's well understood and has evolved over 150 years, has suppliers available for your every need, and can interoperate with standard rolling stock. Seeing how BART turned out they would have done well to stick to more standard approaches instead of badly reinventing the basics.
