Alright. I work with roads and traffic infrastructure, and have never seen that situation before. The active equipment (in my experience) is all stored in above ground cabinets - just simple grey metal cabinets, elevated on foundations or p

What is wrong with the traffic lights in your city would be the much more interesting question here. Everywhere I know, traffic lights work as long as their power supply is intact

by SECProto 7y ago
Sure, but in the sense that road signs or traffic lights are a wear item. They wouldn't be exposed to the real causes of damage to roads (at least in my area) - transport trucks and road plows. They would need to be replaced at 5-30 ye

Definitely. If it was clear that external beacons were necessary, you would have the Tesla beacons, you'd have the European manufacturer associated beacons, you'd have the Japanese manufacturers associated beacons... installed at

Paint is a wear item, the example of beacons would not be a wear item. If original commenter is correct that infrastructure meets halfway, I wouldn't expect self driving cars transition to happen fast at all - maybe on highways first,

And the Tesla Roadster was just a modified Lotus Elise. Buying an of-the-shelf product and reverse engineering it, before building ones' own, is a very valuable step.

It's strange that this article says "Toronto area" - it was sent to the entire province of Ontario.

The title and one place in the body call it 500 acre, while one other place calls it 500 mile. 500 square miles is 320,000 acres. (500 miles) squared is 160,000,000 acres. One other place in the body refers to 1,600,000 acres being viable t

In a city where the availability of land is a major limiting factor, you could argue that cars are the ones getting an "unfair advantage" - 8 square meters of city surface permanently dedicated to moving oneself around is clearly

I can only speak from my experience: Yes, it's cheap, but it's not the cheapest around. It tends to be in the 500-1000Y range depending on toppings. But that range also describes a great variety of restaurants in Japan: soba, tei

Power (kW) determines takeoff weight (ie plane size/passenger count), energy (kWh) determines range. This article doesn't have all the info needed to say how this would scale. For instance, if the energy storage of the batteries d

Nuclear submarines use highly enriched uranium as a fuel. That's not a practical thing to use in civilian reactors.

I agree that's what it looks like. Interestingly, during fabrication, the bulkhead was attached to the ring, and then the whole ring was lifted up and welded on. Maybe there was interaction of the heat affected area from the two welds?
