    Putting aside any media outlet’s take on this, yes he’s wrong but not for the reasons most fans and “futurists” would likely consider. First and foremost, any safety critical system must have backups built in. Backup sensing technology will hopefully be a required component in any future authority approved system. Sadly, I expect Europe will once again lead in this area and the US/Canada will lag far behind.

    But just the technology of lidar itself is vastly superior to visible light camera systems in many instances. Different waves can peer through fog and smoke, high quality DSPs can filter out things like precipitation, lidar brings the light it needs to operate while cameras rely on ambient light or headlights. Lidar also receives speed and distance data as results from point clouds without any need for motion estimation.

    It’s also likely that radar will be a requirement in any serious system, even thought lots of people point out some older arguments against radar. The fact of the matter is, even thought it’s low resolution because of wavelength, repeated measurements can increase the effective resolution. And again, radar brings the energy it requires for its operation rather than relying on ambient conditions, it sees through precipitation, fog, smoke, it can be used at greater distances than visible light or even lidar systems.

    I also think high quality IR cameras would be an amazing addition to any sensor suite because they can detect objects approaching the edge of the road like animals coming out of fields and forests. Something that kills people somewhat frequently, and visible light cameras have a hard time with at night.

    Basically, the number of additional sensors isn’t actually a detriment to automated or assistive driving packages, they are a benefit. Attempting to produce the least expensive system by removing sensors here is equivalent to building a submersible vehicle out of carbon fiber. We know the result before anybody ever attempted it.

    It’s disingenuous to compare a Tesla care that has far less autonomous capabilities with a car that is fully driverless. Tesla cars are more of a stopgap between “normal” cars and fully autonomous cars. To compare a Tesla car that requires a driver behind the wheel and one that doesn’t is, in my opinion, a silly comparison. Of course they will have different levels of required sensors.

    I agree that if LIDAR is too expensive, it’s a hindrance into the changeover from “normal” cars to more self-driving cars for the average consumer. But again, to compare a car that has it’s design goals to be for the average consumer based on price and a car that has it’s design goals to be fully autonomous is silly.

      Of course it’s disingenuous to compare an ADAS and an ADS vehicle, but certain Tesla marketing personalities do it constantly. I’m not even sure I’d be generous enough to say that Tesla’s system is a stop gap between ADAS and ADS since it’s only a very basic ADAS in the first place. 🤷‍♂️

      It’s disingenuous to compare a Tesla care that has far less autonomous capabilities with a car that is fully driverless.

      The CEO of this company was saying “Coast to Coast full self driving”

      “Our goal is, and I feel pretty good about this goal, that we’ll be able to do a demonstration drive of full autonomy all the way from LA to New York, from home in LA to let’s say dropping you off in Time Square in New York, and then having the car go park itself, by the end of next year,” he said on a press call today. “Without the need for a single touch, including the charger.”

      This is a quote from 2017. Elon Musk has never stopped claiming that Teslas will do this.
