so, you're saying it would be impossible to fake the demo with, for example, a remote driver?
But of course we know Zoox is actually driving on SF roads according to public documents, and the fact you can watch them drive if you are in SF and know where to look. Demos are demos, but this one happened with Zoox software at 100% autonomy.
Coincidently Ericson and KTH (which Zoox has cooperated with) has done remote driving over cellphone links over multiple miles. https://m.youtube.com/watch?v=cvSM7pbqZEM
I'm not saying it's what happend. I mean Darpa challange was not fake so Stanford has delivered in the area. But it's possible to solve the lag issue.
