A: The cost of the lessons!

Ride ends but the car signals it can't move? Message the last rider "you forgot to close the door, we'll bill you $1/minute until you fix this".

There are perfectly viable commercial alternatives. I learned home improvement from Tim Taylor, and I've only died 42 times so far.

I compared to wafers because semiconductor wafers are made from a single crystal of silicon which has to be grown gradually, just like these CZT crystals.

The article contains some details on the production process. Each detector consists of a single crystal. This has to be grown, starting from a molten CZT mixture, in a process that takes weeks. It's likely the process can be scaled up, similar to how silicon wafers used to be made from a crystal with a diameter with a few centimeters, and current wafers are 30 cm or more.

I think we're at the point where more people are killed because the incessant beeping drives them crazy, than are saved because they weren't paying attention until they heard the beeping. My flat's being renovated for the past 8 months, and I'm seriously contemplating sabotaging the fucking horns on all the construction equipment.

Only if Bugs hasn't stolen the the Iludium Q-36 explosive space modulator.

That won't help. Such a backup and restore keeps all your account data intact. So you end up with the same account and the same restrictions on a new device.

Yes, braking less quickly can be a plus. That switch has nothing to do with the brake pedal: it changes what happens when you let go of the throttle. An ICE car will slow down using the resistance of the engine (engine braking). With an electric car, you can simulate this by switching the motor to generator mode.

Some people like to be able to coast with no engine braking, others want to be able to do one-pedal driving where letting go of the throttle will rapidly slow the car down, even to a standstill. And some people like to switch between the two depending on road conditions.

It's possible my number is from before 2020 and the global supply chain disruption.

You underestimate the economies of scale. Shipping one t-shirt from China to the USA (as part of a bulk shipment, not as an individual package) costs one cent.

It's much more sinister than that: it's a Grue Jay.

Libris is a Dutch umbrella site for independent bookshops, with a similar arrangement: One webshop that allows you to link purchases to your local shop so that's where the profit goes. Order books online for pickup at the local shop. And ebooks, again with profit going to the local shop. Their catalog is large enough that I can avoid Amazon entirely.

Absurd acceleration is a side-effect of wanting to do as much of the braking as possible with the electric motor. Because braking often happens at much greater decelerations than 60-0 mph in ten seconds, this means you end up with a motor that is much more powerful than you need on the acceleration side of things.
