Am riding in an OG geofrenced autonomous vehicle, otherwise known as an airport monorail. 🚝

Gary Marcus humorously describes riding an airport monorail as an example of a geofenced autonomous vehicle, highlighting how existing transportation systems already operate with limited autonomy within restricted geographic boundaries. The post uses this real-world example to contextualize the capabilities and constraints of current autonomous systems, suggesting that true autonomous vehicles operate within carefully defined operational domains rather than in completely open environments.
