A recent article on automatic closing doors for robocars argues that the car must be able to close the door, because the passenger might leave it open, and the car can't drive with an open door.

Today, Lyft announced a $299/month subscription plan which isn't really very good, but it opens up the discussion of how people will switch to robotaxi service from car ownership, a subject I was already debating in my own household.

We have a bunch of new robocar news recently -- it seems that is a common event. Here's the relevant stories, plus some notes on robocar doors.

I love to talk about the coming robocar world. Over the next few decades, more and more trips will be made in robocars, and more and more people will reduce or give up car ownership to live the robotaxi life. This won't be instantaneous, and it will happen in some places decades before it happens in others, but I think it's coming.

But what of the driver of the regular car? What lies ahead for those who love driving and want to own a traditional car? I often see people declare that nobody will own cars in the future, and that human driving will even be banned. Is that realistic?

This week I attended the "Revolution.Aero" conference on advanced new ideas in aviation, including electric VTOL aircraft (often called "flying cars.") I learned that there's a lot of interesting new stuff going on in aviation, but the strong regulatory environment keeps much of it repressed.

Update 2019: New research suggests the incremental cost per mile of electric robocars is low enough to alter some of the logic below. An update is in the works.

In the world of electric cars, some people talk about an idea called "vehicle to grid" or V2G. Renewable energy's biggest challenge is storage -- wind and solar only come at certain times of the day, but we need electricity all day. The V2G hope is to use all the batteries in electric cars as a means of grid storage.

How will robocars and pedestrians interact?

My article last week on Sleeper cars generated lots of interest, and Volvo's concept car generated lots of press too. Some of it was quite negative, including a article provocatively calling them the dystopian future we must prevent. I thought I would revisit some of the things about such vehicles that run quite counter to the intuitions of those used to 20th century transportation and transit.

Yesterday, Volvo got some good buzz for a concept car which included a bed for sleeping and asking the question "why fly when you can be driven?". I've written about sleeper cars before, as well as the full robo-RV, but let's put all the issues together.

I rarely just link to another story, but today I will point all to Aurora's post on its development philosophy. I think it contains some important lessons for all in the field.

A couple of years ago I released my list of factors by which robotaxi companies might compete. Many people wonder if there will be a natural monopoly, limiting us to one or two companies per city, or if we might get more.
