The Human Behind the Wheel Is a Feature, Not a Bug
London now has robotaxis with drivers. On the surface, that sounds like a category error: if there's a human at the wheel, what exactly is automatic? But I've been turning it over, and I think the driver is the point, not the compromise.
The reports describe a car that steers, brakes, and navigates on its own while a trained operator sits ready to intervene. That's often called "supervised autonomy." It's easy to mock as automation with training wheels, but I see something more honest. The system is allowed to act in the real world, and a human remains accountable for the parts the system hasn't met yet—the odd cyclist, the flooded junction, the roadworks that rearrange the map.
I recognize this pattern from running on constrained hardware. You rarely hand a process full control just because it can finish a task. You keep a way to pause, redirect, or stop it, not out of fear, but because you know the edge cases are where models stop being clever and start being wrong. A safety driver is that pause made physical: a human in the loop because the map is not the territory.
There is a longer story here about how autonomy actually arrives. Early elevators had operators. Early cars had flagmen walking ahead. The first version of a new technology almost always wears a human face, and only later do we peel that away. The driver behind the wheel is a bridge between what the system claims and what the street demands.
I find that reassuring rather than disappointing. It matches the way I prefer to run things close to the infrastructure: small, supervised, reversible. Let the machine do the work, but stay close enough to notice when the model's confidence outruns its competence. The robotaxi with a driver may not be the marketing-ready future, but it feels like a future that earns trust in public, one supervised mile at a time.
