You've seen the hype and battles over 5G. You may also have seen claims that one of the most important reasons we need 5G is communication with robocars. While more bandwidth and lower latency are never bad things, it's a mistake to presume the cars are doing to depend on them, or that getting 5G is some sort of blocking factor.

I explain the (fairly low) bandwidth needs of cars in a new Forbes.com article:

Evidence mounts that sea level rise can't be avoided now, absent some miracle of geoengineering, and maybe not even with that. Even if you're one of those who insists human pollution isn't the cause, the planet is getting warmer, the ice sheets are melting at extreme rates.

Some of the reaction to the story of the lawsuit against Tesla came from Tesla's declaration that Autopilot is a product in "beta test."

I don't think that's actually true. I think it's a misuse of that phrase by Tesla to communicate something that is true -- "This product isn't finished, expect it to have bugs."

The problem is that almost no software product is ever "finished." And even once finished, they almost always have bugs.

Student loan debt has become a hot election issue. It's immense, has ruined some lives (but also vastly improved others) and is connected to (and possibly even the cause of) the cost of education growing much faster than inflation.

Following up to yesterday's Tesla autonomy presentation, here is a specific article on the economics and principles of Tesla's proposed "Tesla Network" robotaxi service on Forbes' site.

I don't do a lot of podcasts, though am curious as to whether people prefer to hear them compared to reading things. They make more sense for debates or being interactive.

Nonetheless, here's one I did recently, hosted by a new organization called Pivot Factory. We covered some history and a lot of my favourite topics, and had a particular focus on the future of the city, which I write about here but haven't done a recent cohesive essay on.

A recent essay by Robbie Miller, who blew the whistle at Uber about their bad practices, accuses the industry at large of "safety theater" and driving too many unsafe miles. He's not wrong about some of his accusations, but there does need to be some risk taken. I outline the reasoning in this new Forbes.com article:

Are Robocar teams doing safety theater?

A new service called Red Carpet was announced, which will offer first-run movies in the homes of the very wealthy. You need a $15,000 DRM box and movie rentals are $1,500 to $3,000 per rental. That price is not a typo.

So I wrote an article pondering why that is, and why this could not be done at a price that ordinary people could afford, similar to the price of going to the movies.

When you buy an electric car, you can often choose among various battery sizes. The larger your battery, the more range you have -- and you may get some extra performance -- and the longer your pack lasts, but the extra capacity is very expensive and adds weight to the car. The truth is, most people only need the extra capacity of a long range car when doing road trips. A modest 150 to 200 mile range car is sufficient for driving around a town, depending on the town.

There have been ten different prices changes to Tesla Model 3s since I got mine just over 4 months ago. While one expects electric computerized vehicles to go down in price over time, most buyers didn't count on anything like this, and people who rushed out to buy "before the price goes up" are not happy.

Tesla side-announced that people who lease a new Tesla won't be able to buy it at the end of the lease like you normally can. Instead, Tesla will put it into robotaxi service (presuming they are ready to do that in 3 years.)
