4. I suspect that we in Ottawa-Gatineau are in particular danger of having our public transit funding undermined by that kind of thinking. It is indeed a blind spot on Musk's part, and a lot of cities can't afford to adopt it.

14. That particular Polish law proposal is another of their problematic actions in the last half-decade.

16. Loved that report. "You want that sandwich? Come to the South Pole to get it!" :-D

17. A good ending to a long musical dispute.

The guy's not bothered to look at: https://www.boringcompany.com/faq/ Note the... "Loop is a high-speed underground public transportation system in which passengers are transported on autonomous electric skates traveling at 125-150 miles per hour. Electric skates will carry between 8 and 16 passengers (mass transit), or a single passenger vehicle." In other words, Musk is providing for mass transit, and that guy is an idiot.

Until then though, I'm of the opinion the humble motor scooter could help a lot with current congestion. Unlike bicycles, they can share the road with cars because they go as fast as cars. Watch this cam for a while, preferably during rush-hour, to see what I mean...

The Victoria line, the busiest line on the London Underground runs 36 trains an hour. One every 100 seconds or so. Those trains are 2009 Tube Stock which have a capacity of about 1,400 passengers. That's mass transit.

I agree with Jarrett Walker.

I've always been fond of the remark that a civilised city isn't one where the poor people have cars but where the rich take public transport.

I think the cost advantage of removing the driver favours public transport, especially along with some sort of organised ride sharing for the last half a mile of a journey.

Smart cities and polities will side step the messy conversation about whether the lower middle classes can all ride round in robot chauffered cars all the time and just move to putting in cheap, plentiful mass transit with some 21st century gloss.

Every time I read something that Musk has said or written about Hyperloop and his tunnel company I think to myself "Well done, you've invented the subway." And I'm fine with Musk putting a lot of money in to digging tunnels, running them inefficiently, going bust and then someone using the tunnels as a bus lane.

In Musk's defence, if he's correct that he can significantly lower the cost and time of digging tunnels then that might turn out to be really useful. Having 4 tunnels under Princes Street with a couple of underground stops on each would probably sort out our bus problem.

Some thoughts on the 15 year trend.

The developed countries in the world probably have about as much large-scale hydro as they can. Except perhaps Norway.

I wish I understood the nuclear industry. They seem to have lost interest in selling to the West.

I think the question over the next 15 years is going to be how to solve the problems that let you fit more cheap renewables on the grid without spending all the money on capex.

Also, over the next 15 years we'll discover what the longer term degradation factor for solar PV is. That's going to be an interesting number.

Texas is a most peculiar place. Imagine not having interconnection with your neighbours.
