Very very few LNG cars and trucks out there, as filling infrastructure is limited compared to CNG. In US it's something like 2% of total CNG+LNG fleet.
Interviewed with a midwestern company doing CNG truck conversions and building fueling infrastructure back in 2014/15. Diesel prices coming down crushed them, and they sold off the majority of their fueling station biz in 2019, to focus on renewable CNG from dairy & hog farms.
