> and have existed for several decades Except that they are not really cheap, safe, or convenient. They are not door to door. Public bus/trains run at their own scheduled time, not at my desired time. Even services like Uber involve humans who are more concerned about their profit than my schedule or preferences, so they cancel rides when I need them the most because some other ride is more profitable for them. Moreover in countries like India where road accidents are the highest in the world, rash and unsafe driving is a big problem (government run bus, car drivers or private ones). This can just wipe that out! So personally, I'm super excited about this future.
