Tesla "Full Self-Driving" Beta released

@taiwan_girl that's interesting. Not unusual to be driving the "expressways" in Chicago and things slow to a crawl for no apparent reason. I just shake my head and wonder what that was all about. This makes it a bit more clear.

Also, the psychology of driving in "wolf packs." If you look at how traffic is bunched up on expressways, you'll see it come in waves (assuming the flow is steady and fast). I try to stay between them.

There was a spot on I-395 near the Pentagon where the traffic would always stall during rush hour.

The weird thing was that it would stall even when it wasn't rush hour. The limit was 55 but light traffic at midnight would still go 40. I think it became a habit.

You would think that if the number of lanes stays constant and everyone went the same speed traffic would move without delay, barring accidents, etc. Perhaps that is where this will take us.

Yes, definitely.

While spending millions of hours sitting at Northern Virginia stoplights, it was obvious to me that the roads had tons of unused capacity. Everyone was just sitting at stoplights while most of the pavement gathered dust.

It is even more obvious from the air. Route 7 looked less than 50% utilized at evening rush hour. But I know from the ground you were sitting in a pack, looking at each other, slowing for the next light.
