I suspect price is still the driver (pun intended) here. Flash LIDAR is, for the most part, shockingly expensive. Some companies like Toyota are looking into bringing the cost down with CMOS SPAD arrays, but it's still very much lab work. Similarly the Velodyne system ain't cheap and was close to $80k not too long ago. Stereo is pretty much free, but still needs more work to make it robust enough. Even smaller line scan LIDAR units (e.g. the SICK LMS models) are around $5k each.
