Vibrations are surely an issue with electromechanical systems but hardly with electronics. There are plenty of cheap electronic accessories for cars and you can observe that those keep functioning for years.
Sure, these are the assumptions but silicon is silicon, copper is copper and solder is solder. They don't use easy melting electronics in vacuums and hardened stuff in cars, the tech is about the same unless it is supposed to work in highly radioactive environment. The plastics are different but car interiors are full of plastics, so its unlikely that the costs of temperature resistant plastics needed for this is more than a cupholder.
As for the range, again pretty powerful lasers are sold for sub 10SUD prices on retail. I am sure that there must be higher calibration and precision requirements as the distance increase but is it really order of magnitudes higher? 120 meters laser measurer with 1cm accuracy is 15 Euros on Temu and that thing has an LCD screen and a battery as a handheld device. How much distance do you actually need?
There are laser measurers sold for a few buck on Temu. Robot vacuums sold for few hundred dollars have Lidars that map out the room in a seconds.
Is there any actual technical reason why automobile Lidar be expensive? Just combine visual processing with single point sampler that will feed points of interest and accurate model of the surroundings will be built.
I recall Shaun Maguire trying to interfere with European politics, specifically supporting AfD in Germany. Instantly lost my admiration towards Sequoia, the image I previously had about them was something like calm, deeply analytical grown ups. Turns out they are into petty daily politics that will not go anywhere other than stir drama, at least this Shaun guy. Still feels bad when I think about it, disillusionment is painful.
