250$ LIDAR is on the horizon http://driverless.wonderhowto.com/news/quanergys-new-250-sol...
A seven layer seal? That could surely only be broken by the darkest of magics.
With regards to the missed shipments - I agree, that is a red flag. And when a company gives a timeline, and then that passes and they change their answer to "soon" it's concerning. Of course, it's CES right now - maybe someone will make an announcement in a few days. Last year Quanergy hyped up their sensor, but when they were pressed it turns out their demo sensor was actually not solid state.
