In a quirky development, tech workers have begun leaving notes in robot taxis, turning these autonomous vehicles into makeshift message boards where people can seek connections for work and romance. Users have commented on the potential downsides, such as the commercialization of this trend and concerns over privacy, as well as the idea that this method resembles a modern-day 'message in a bottle.' While some see this as a fun experiment embodying human creativity, others worry it indicates a decline in genuine human interaction. Additionally, there is speculation about the inevitable introduction of advertising on screens in autonomous vehicles, reflecting patterns seen in Google's history with monetization.
