  • Two facts:

    1. The average occupancy of a car in my North American city is 1.2 people per car. This does not vary much by city.
    2. Autonomous vehicles will almost certainly be worse for traffic than human driven cars. They will circle empty with no passengers and drive to pick up passengers empty (dead heading) even with a fully rideshare system. If there is widespread private ownership of autonomous vehicles (and you bet your butt that car companies will campaign for this aggressively to keep sales up), the dead heading problems only multiply. If you don’t believe me, look up any recent literature on the topic: by most accounts it will be worse, not better. Dead heading is only the tip of the iceberg of problems there.

    I have definitely had this experience in KSP and never really thought about until this comment. Neat!

    However, there is a practical reason the Apollo mission orbited on its side like this. The side of the spacecraft facing the sun would get very hot while the side facing away would get very cold. So the spacecraft would roll slowly as it travelled for passive thermal control. They literally callrd it the barbecue roll.

    Orbiting a planet along it’s equator means orienting north/south (normal/antinormal) for a natural roll axis. Neat stuff!

    Nobody’s life is in any real danger here. They and all their equipment are roped in on at least 3 redundant anchors (probably a number more). Rock climbing looks scary but with proper precautions and training it is not significantly riskier than other outdoor sports.

    The level of ignorance from these commenters who know nothing of the sport but speak with such authority on it really reminds me of the worst of reddit.
