Embedding sensors in the roads, street signs, and furniture - isn't that going to make more sense than turning ever vehicle into a super-computer? This would require a broad agreement on a global standard for Infrastructure to Vehicle (I2V) and huge investments by local and national governments around the world. It could technically happen, but likely will proceed at a snails pace. As you mention, it would be much better than relying on-board sensors like Lidar and cameras as centimeter accurate GPS coordinates can be embedded into road signs etc, but it will take decades.
