It different from Waymo because Waymo uses Lidar and Tesla's do not. That is not exactly accurate, Teslas use Lidar, but only when training their software. They do not use it as hardware on the car like Waymo.
This difference is a huge difference. The difference is huge, because Lidar is expensive. Tesla only uses 7 or 8 cameras, which happen to be very cheap. Their advantage is in the software.
Tesla will have a massive cost advantage over Waymo if they are successful in making robot driving more safe than human driving. Many analysts think the cost advantage is so large that it will put Waymo and possibly Uber out of business. Waymo and Uber have teemed up to try and compete against Tesla (after Tesla rebuffed Ubers offer to work together)
RoboTaxi and Cybercab are different things.
RoboTaxi in my opinion, is any tesla running the FSD software. The CyberCab will be a low cost car designed specifically to be low cost and serve as a taxi.
If anyone wants to listen to me, THE SOFTWARE ALREADY WORKS. I am telling my TI brethren this in hopes of making them money.
I can get in my car right now and arrive at my destination by only pushing one button for 2 seconds. I do not have to touch the pedals or steering wheels, at all.
The implications of this, to me, are huge. It opens up more time for productivity. Instead of driving, you can be scheduling appointments, trading stocks, doing work, resting. More productivity = More money.
