I mean, there’s no problem here. In fact, I think it’s super sensible to make this a 2 seater.
Clearly their plan is ultimately for this robotaxi service to be something you can run on any Tesla car. Meaning that the majority of cars on the service will be 5 seaters.
On the other hand, I’d bet anything that the vast majority of rides requested are for a single rider. So if you’re going to make a vehicle specifically to be the optimal car for this purpose, it should definitely be a 2 seater. Smaller, lighter, better mileage, cheaper. If you need to order a ride for more people, a different car can do that and there are more of those available anyway.
The only gripe i have, is that this really could have been a 3 seater. Generally cars have adjustable front seats because the driver needs to be able to reach the pedals comfortably. But since that isn’t an issue here, it would have made a lot of sense to make it a bench seat just like most cars have in the back. Then again, the car does look quite small, so perhaps making it a 2 seater helped them constrain the size a little bit more.

You’re missing the point, nobody is talking about trusting these companies.
You can tell if a connection is encrypted end to end or not. And if your paying for that service you can sue if you aren’t receiving what your paying for.
In digital security nobody relies on trust if they can help it. And security matters if you want to keep a competitive edge on your competition, so even shitty companies care about that.
