It's an interesting discussion that I don't have time for right this moment, but I will say that simply holding the opinion that you highlighted isn't by definition unreasonable with the state of technology today. Whether that opinion is arrived at honestly may be open for debate.
Indeed, there are quite a few current developments which attract different opinions. Many debaters are not aware of the latest discoveries and blindly quote ten year old axioms. There is a lot of relevant information on the latest automotive and industrial breakthroughs on youtube and other platforms dispensed by very knowledgeable people who cover these developments in a timely manner and in a great detail. Here is a short list of the top such channels/youtubers - Tesla Daily, Dr. Knows It All, Munro Live, Now You Know, Warren Redlich, Electric Viking, Electrified, E for Electric. There are many other similar channels with slightly different topics and somewhat less competent reporters.
As to the "not unreasonable opinion on vehicles driving without Lidar", it might be useful to know that Google Waymo which in 2017 developed and started to sell their own brand of Lidar. called "Laser Bear Honeycomb", has now abandoned and stopped selling this equipment. Google (or Alphabet) spent so far over $3.5B on the Waymo project which has been a total fiasco when compared to other competitors in this field. Meanwhile the Tesla company which initially also used Lidar, found out through extensive in-field experience that their Self Driving system is much more effective using pure vision rather than relying on a mix of different sensors.
