Lidar vs. Tesla: the race for fully self driving cars

so if you'll recall way back in 2018 waymo sued Uber for stealing trade secrets so there's no trade secrets gonna be shown today that's what you came for too bad waymo is the self-driving car spin-off of Google and Uber was also working on self-driving cars at the time Uber's Chief Tech bro Travis kalanick was questioned on the stand about a weird phrase that he wrote on a whiteboard during a late night Jam sesh a phrase I don't really appreciate having to say out loud on camera but here it goes laser is the sauce I also don't really enjoy having to say jam sesh but that's beside the point that phrase spawned some terrible memes but it got to a core belief that's helping power the development of self-driving cars a huge multi-billion dollar science experiment that could potentially change the way we get around forever and that core belief is that lasers or rather lidar is the secret sauce that could really crack this incredibly complex problem of autonomous vehicles wide open there's a big debate between companies who use lidar and the one company that doesn't and it all comes down to a question how self-driving do we need our self-driving cars to be I'm Andrew Hawkins and this is your status update foreign before we get to that we have to address the autonomous elephant in the room a lot of people think that self-driving cars are just fully a scam that they're basically vaporware from billion dollar companies who have been promising a fully driverless future for decades but never delivered all those viral clips of self-driving car fails in San Francisco certainly help paint this picture yeah we got a cruise vehicle nobody in the car no place for us to go off There's No One Drive no self-driving cars are not poised to suddenly take over the world and yeah the AV industry is struggling thousands of employees have been laid off timelines has stretched into the future with no visible endpoint some companies have even shut down completely after losing all their funding but true driverless cars companies like waymo and Crews they're in San Francisco and Phoenix and they're picking up real passengers and taking their money for trips right now and part of the reason that they're able to navigate these complex environments is because they use a lot of sensors including cameras radar and ultrasonic sensors to create 3D renderings of their environment but most critically they use lidar Travis kalanick's laser sauce lidar stands for light detection and ranging it works by sending out a pulse of light waves that bounce off of objects and return to the sensor lidar uses the time it took for each pulse to return to the sensor to calculate distance traveled and that way it can measure how far away an object is a typical lidar pulse contains thousands of beams of infrared laser light these pulses create Point clouds which can be used to create 3D renderings of the environment the result is a much more detailed 3D map of the world than cameras and other common sensors can offer it even works at night when cameras alone are essentially blind cars like waymos still use the full complement of sensors in the vehicle's brain fuses all the data together to get the best possible view of reality lidar isn't just for autonomous cars lately it's been showing up in a lot of different places like iPhones and iPads and the New Vision Pro augmented reality headset that Apple just unveiled it's being used in farm equipment and Warehouse vehicles and in aviation lidar companies like luminar are working to put their sensors into vehicles that you can buy yourself lidar is going mainstream but not everyone thinks that lidar is the sauce yeah Tesla the most aggressive company in pushing autonomous Tech on its customers doesn't include lidar in its vehicles in Elon Musk has been talking all kinds of trash about lidar in recent years here's what he said in 2019. anyone relying on lidar is doomed expensive sensors that are unnecessary it's like having a whole bunch of expensive appendices today's Google's approach which includes lidar in NBC interview from earlier this year he bragged that Tesla's vehicles are more powerful than Google's because they can drive in more places so flightar is so powerful what's that about well Tesla's vehicles used to include a bunch of different sensors but Elon Musk decided it was too complex and too expensive so he ripped everything out but the cameras the truth is that lidar just doesn't work for Tesla's business model Elon Musk wants to sell cars to lots of people cars that he promises will become fully autonomous someday but including lidar would just make them too expensive for most people to afford now the price of lidar has dropped dramatically in recent years from around 75 000 a pop to now around six thousand but the tech is basically incompatible with Tesla's balance sheet for all of elon's claims about the future Tesla's present Tech is still just driver assist autopilot and full self driving still require the driver to pay attention to the road and take over when something goes wrong and when it does the driver is the one liable for whatever happens if a weibo or Cruise crashes the companies are liable for the damage in other words Robo taxi companies aren't selling cars to people so they can afford to add lidar to their vehicles Tesla still needs people behind the wheel because it needs people to buy its cars waymo and Cruz just need people to ride in them that's the difference that lidar makes another difference is car crashes more specifically the severity of the crash when waymo Vehicles crash they tend to be pretty minor like low speed rear end collisions the company only reported two crashes in 18 minor contact events after driving 1 million fully driverless miles in California and Arizona the number of people injured in those incidents zero the number of people injured in Tesla vehicles using autopilot very much not zero according to Federal crash data Tesla vehicles using autopilot were involved in 736 crashes since 2019. 17 people died in those crashes including 11 since May 2022 experts told the Washington Post that the removal of some sensors including radar appear to have contributed to the increased number of incidents now there are a lot more Tesla vehicles on the road than waymo vehicles and Tesla's aren't geofence to specific areas like waymo and we're not saying that radar or even lidar would have prevented any of these crashes from taking place but if you're comparing the two companies waymo's cars arguably can see more of the world than Tesla's and that's partly because of the sensors so what happens if lidar suddenly becomes so cheap it pays for itself will Elon flip-flop on his lidar skepticism musk isn't anything if not unpredictable but that would be a huge reversal on his part if he went and added lidar to his cars but if he wants Tesla to ever be fully autonomous not just use fancy driver assist systems like autopilot and full self-driving he may have to accept lidar in his heart it doesn't have to be the hole sauce but it certainly could be one of the most important ingredients I'm sure you're tired of listening to me talk about sauce but we'd love to hear from you about self-driving cars do we need self-driving cars there's lots of questions about the relevancy of driverless technology so let us know what you think in the comments below
