Lidar costs have dropped massively and continues to drop. Waymo, for example, claimed 4 years ago they were able to reduce cost of their Lidar by 90% from $75,000 to around $7500 [1]. In the meantime, range and resolution of these sensors have increased. Anyone not making use of Lidar in this day is just hamstringing themselves.
