Sanity Checks on the promises being made...
Far too many people are just granting the assumption that fully autonomous cars will be fantastically, almost perfectly, safe. This is in spite of the famous failures (Tesla, Volvo, others...). Okay then, so no speed limits on autonomous cars? Let them careen through the city as fast as their little "Strong AI" pea-brains will allow them. LOL...
Another idiotic assumption is that having shared vehicles that fail to stop and park when not occupied will somehow, magically-inherently, diminish congestion on the roads and somehow save energy and emissions.
Allow me to explain the issue:
M = A-to-B + Y-to-Z (morning) + B-to-A + Z-to-Y (evening)
N = A-to-B + B-to-Y + Y-to-Z (morning) + Z-to-B + B-to-A + A-to-Z + Z-to-Y (evening)
News Flash: N > M
This: Shared vehicles (autonomous or taxis) need to relocate when empty. Think about it.
Perhaps there may be some secondary or tertiary effect will counteract this obvious fact that N>M, but that's all hand-wavy magic. Too many people just gleefully assume the opposite of the direct primary effects, because they're not thinking. Telephone Sanitizers all.
