But they do, there are literally cars out there with lidar sensors.

The question was why can't I have a lidar sensor on my car if my $150 vacuum has one. The lidar sensor for a car is more than $150.

You don't have one because there are expensive at that size and update frequency. Sensors that are capable of outdoor mapping at high speed cost the price of a small car.

The manufacturers suspect and probably rightfully so that people don't want to pay an extra 10 - 30 grand for an array of sensors.

The technology readily exists rober had one in his video that he used to scan a roller coaster. It's not some conspiracy that you don't have it on cars and it's not like it's not capable of being done because waymo does it all the time.

There's a reason why waymo doesn't use smaller sensors they use the minimum of what works well. Which is expensive, which people looking at a mid-range car don't want to take on the extra cost, hence it's not available
