Do you think that SDV is a bit (just a bit) in a kind of skeumorphic zone where mobility was defined by human driven charriot and thus computers are having to replicate all the complex human perception and control.. while, in urban settings, we could pave the roads with markers and beacons so that moving objects could move around without all the sensing technology ?
What you're describing is a reliability nightmare.
Human drivers 'depend' on road markings, but if some paint gets scuffed or a stop sign blows down in a storm, things still work okay. For AI cars to be similarly fault-tolerant, they need to be generally capable drivers who don't absolutely need exacting external markers to get around.
You can't pave roads with markers and beacons to do self-driving without simultaneously banning all non-AI traffic participants, including pedestrians.
