My theory is once the novelty wears off and the high tech jaguar carriage is eating margins, public robo taxis will be about as fun to ride in as a public toilet. The lack of a person and the social pressure that implies (and legal protections) means people will do just about anything in the robotaxi. Cameras and deplatforming will work for a while but it’ll turn into more an accumulation of small things - spilled drinks, garbage left behind - then eventually it’ll be a race to the bottom where most people ride in relative filth while people continue to private cars because they want to avoid sitting in semen stains.
