A new car look without steering wheel and pedals. A working robovan. I don't think people understand the complexity of creating a hardware prototype of anything. This can't be ChatGPTed
They've shown working shells of cars at every single reveal of their past cars without the interior filled in. We know they can do that. What's in question is whether they can make a driverless taxi.
The demo is open to the eventgoers and lets you choose your destination. It's quite polished and a lot more advanced than "hardcoding to drive in a loop".
