Scooters are so efficient we should fix them, not ban them

Scooters from Lime and Bird have been causing a stir as they move quickly into cities. There's been blowback, because riders travel recklessly, often on sidewalks, and they also leave scooters just lying on the sidewalk, blocking things, because as dockless scooters you can drop them anywhere. Riders are also getting hurt, these are not the safest things to ride.

So cities are striking back, trying to stop, regulate or collect money from these scooter operators.

To discuss transportation, we must agree on what the goals of a transport system are

Busy Argentine bus stop

People love mass transit. By this, I mean there are a lot of people who, either for historical or emotional reasons, love transit as a good in itself, rather than a means to various ends.

Flying cars, robocars and more will rewrite the rural landscape, for good and ill

How and where we live is governed most by transportation, and all the new mobility technologies are poised to cause big changes. Today, I want to look at the following technologies and how they will affect life outside the city. In many case, they will come last to the country, but in other cases, they may come first.

Where's a fireproof rescue vehicle?

Everybody here is in shock over the destruction and death from the recent California fires, and I, like many, have even fled the coast for the mountains as the air in the San Francisco Bay area remains unsafe. Videos of people escaping down burning streets send chills into those who watch them.

Lidar report details all the players

Earlier this year this nice summary of LIDAR companies was published. While it misses a few projects, I recommend it as a nice visual overview of the many LIDAR technologies in production and under development.

Time to rebuild this body

After elections, Americans lament about the current structure of the Senate (and electoral college) because they are based on legacy, and do not follow the principle of one person one vote.

Sex in your robotaxi

I decided not to use a photo with this article

A Washington Post article suggests robotaxis may become popular for sex on wheels. In my talks I have often made the joke that while the auto industry quests for "Vision Zero" -- no automotive fatalities -- the robocar is the only technology that could result in people actually being created while driving.

Like many people who have worked in cryptography for decades, and is used to the abbreviation "crypto" to refer to it, I wince when I see that term now being frequently used as a short for "cryptocurrency," ie. Bitcoin and its friends.
