The vapor pressure of methane is about 6.25 MPa. For comparison a bike tire has about 0.4 MPa, a car tire closer to 0.2-0.25. So you need a pretty damn good compressor and pressure vessel / pipeline, versus a simple tank for methanol. Also worth noting that the methanol can later be easily converted to dimethyl ether and used as a cleaner-burning diesel fuel (vapor pressure ~0.5 MPa), where it may be possible to convert existing engines:
