  • A tree is a terrible representation since people will appear in more than one place on it. brother sisters marriages (which did happen) tend to produce deformed kids, but first cousins have good odds for normal kids. By third cousin odds of genetic issues was close enough to zero, but those kids will have six great great grand parents not the mathematical eight. I didn’t mention half siblings but that happens too and a couple generations below could marry safely.

    the above isn’t just theoretical. Before modern transport you often lived and married in the same village for many generations. It would often be impossible to find anyone to have kids with that wasn’t at least sixth cousins from more than one path.






  • Driving is full of edge cases. Humans are also bad drivers who get edge cases wrong all the time.

    The real question isn’t is Tesla better/worse in anyone in particular, but overall how does Tesla compare. If a Tesla is better in some situations and worse in others and so overall just as bad as a human I can accept it. Is Tesla is overall worse then they shouldn’t be driving at all (If they can identify those situations they can stop and make a human take over). If a Tesla is overall better then I’ll accept a few edge cases where they are worse.

    Tesla claims overall they are better, but they may not be telling the truth. One would think regulators have data for the above - but they are not talking about it.



  • Deer on the road is an edge case that humans cannot handle well. In general every option other than hitting the deer is overall worse - which is why most insurance companies won’t increase your rates if you hit a deer and file a claim for repairs.

    The only way to not hit/kill hundreds of deer (thousands? I don’t know the number) every year is to reduce rural speed limits to unreasonably slow speeds. Deer jump out of dark places right in front of cars all the time - the only option to avoid it that might work is either drive in the other lanes (which sometimes means into an oncoming car), or into the ditch (you have no clue what might be there - if you are lucky the car just rolls, but there could be large rocks or strong fence posts and the car stops instantly. Note that this all happens fast, you can’t think you only get to react. Drivers in rural areas are taught to hit the brakes and maintain their lane.






  • It is a proxy for don’t use too much on the busy towers. In small towns it doesn’t matter, but if you are in a downtown the tower will have many people connecting to it and the radio frequencies are shared. By putting a limit on everyone they force better sharing of that limited bandwidth. The limit is very large - far more that than the large abusers will use alone, but in a dense areas it is less than the common person will use all at once.

    Tmoblie has (or had?) a binge on plan - if you used video (which we quickly figured out meant low quality - but probably good enough for a tiny phone screen) or audio you were using a lot of data, but it was consistent all day and so they didn’t have to count it - if the tower doesn’t have enough bandwidth for everyone on the first day of the month they have to fix that. That is the real worry: the tower running out of bandwidth on the first day of the month.
