I think you're suffering from not knowing what you don't know.
Let me make it a but clearer for you to make a fair answer.
Take a .25mw lidar sensor off a vacuum, take it outdoors and scan an intersection.
Will that laser be visible to the sensor?
is it spinning fast enough to track a kid moving in to an intersection when you're traveling at 73 feet per second?
You're mischaracterizing their point. Nobody is saying take the exact piece of equipment, put it in the vehicle and PRESTO. That'd be like asking why the vacuum battery can't power the car. Because duh.
The point is if such a novelty, inconsequential item that doesn't have any kind of life safety requirements can employ a class of technology that would prevent adverse effects, why the fuck doesn't the vehicle? This is a design flaw of Teslas, pure and simple.
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
Only Tesla does not use radar with their control systems. Every single other manufacturer uses radar control mixed with the camera system. The Tesla system is garbage.
yeah, you'd think they'd at least use radar. That's cheap AF. It's like someone there said I have this hill to die on, I bet we can do it all with cameras.
Yeahhh pretty sure I know who
Good God it's like you're going out of the way to intentionally misunderstand the point.
Nobody is saying that the lidar on a car should cost the same as a lidar on a vacuum cleaner. What everyone is saying is that if the company that makes vacuum cleaners thinks it's important enough to put lidar on, surely you're not the company that makes cars should think that it's important enough to put lidar on.
Stop being deliberately dense.
You're either taking to a fanboy or Elon on ket. You ain't gettin' through.
Its weaponized incompetence.
I bet they do the same shit with their partner when it comes to dishes, laundry, and the garbage.
lol, what partner
Whether lidars are reliable enough to run on autonomous cars has nothing to do with whether they are cost efficient enough to run on vacuum cleaners though. The comparison is therefore completely irrelevant. Might as well complain that jet fighters don't allow sharing on Instagram your location, because your much cheaper phone does.
and I think you're suffering from being an arrogant sack of dicks who doesn't like being called out on their poor communication skills and, through either a lack of self-awareness or an unwarranted overabundance of self-confidence, projects their own flaws on others. But for the more receptive types who want to learn more, here's Syed Saad ul Hassan's very well-written 2022 paper on practical applications, titled Lidar Sensor in Autonomous Vehicles which I found also serves as neat primer of lidar in general..
Wow, what's with all the hostility against him.
It's maybe because i also know a bit about lidars that his comment was clear to me ("ha, try putting a vacuum lidar in a car and see if it can do anything useful outside at the speeds & range a car needs").
Is it that much of an issue if someone is a bit snarky when pointing out the false equivalence of "my 500$ vacuum has a lidar, but a tesla doesn't? harharhar".
Because no one suggested that.
