  • How will it reduce demand for parking? Do you envision the car will drop someone off and then drive away until it finds a parking spot that’s farther than the person would want to walk?

    That sounds like a very hard problem , and people wouldn’t be happy waiting 5-10 minutes for their car to navigate back to them. Or it would just cruise around looking for parking, causing more traffic.

    Cars could tailgate like virtual train cars following each other at highway speeds with very little separation, lanes could be narrowed to fit more cars side by side in traffic, etc.

    Once again reinventing buses and trains






  • Not included in this answer and I’m not fully qualified to talk about: salting.

    If you knew the hashing algorithm, you could precompute hashes of all the common passwords. Then when you get steal the hashed password data, it’s a lot faster to check if any of them are in your list. You can likely find that kind of list online to download.

    One defense against this is “salting”. The site adds some text to your password before hashing it. So if your password is extremely common, like “password1!”, with the added salt the hash on this site will be different. Like maybe it adds the user’s uuid, so what gets hashed is “password1!-abcd-123-pretend-this-is-a-uuid”. The user doesn’t need to know.

    Another benefit is that now two passwords that both are “password1!” have different hashes.

    I’m not an expert by any means so please someone correct me if anything was wrong there.


  • I don’t have the means or motivation to do research now from the couch, so I’ll concede you may be correct. However, I think it might be even safer to take those same billions of dollars and invest them in mass transit and other infrastructure changes. That would mean fewer car accidents, less pollution, nicer spaces, healthier people, healthier economies, etc. private car ownership cannot be the long term solution. If it’s not an outright dead end, it’s certainly a side street instead of high speed rail (if you’ll pardon a strained metaphor).
