I don't even get the sense of relief. I could stop 1 second short of finishing and feel no difference.

High functioning and low functioning doesn't describe a person, it describes how much help you need. You can be high functioning on one day and low functioning on another.

A hydrogen engine is so much worse for efficiency than a hydrogen fuel cell, and even that is not good compared to batteries. I'd estimate the round trip efficiency of a hydrogen engine to be about 10-15%. So for the same energy that could be used to drive a battery EV 100km, this car from Toyota could drive 12km.

Additionally, hydrogen is not very energy dense per volume. A compressed hydrogen tank that replaces the boot/trunk of the car would have enough hydrogen for about 100km of range.

Please let me know if I'm wrong about any of these numbers. For Toyota's sake, I really hope I'm wrong.

I find it helpful to break up the text into paragraphs where each paragraph is it's own talking point/topic. It seems easier to read, and easier to find information when re-reading.

Other things I've found helpful:

• A main paragraph with succinct information
• Follow-up paragraphs explaining the first
• Dot points

The follow-up paragraphs should not have any new information in them (e.g. date/time, locations of events, tasks to be done). They should be for clarification, so that only the first paragraph(s) need to be re-read to find all the important information.

This is just my experience. I am not an expert.

This is the worst thing I have seen all year.

I've worked in IT. You are most likely correct, and anyone with any sense would do it that way, but I would absolutely believe that someone could be incompetent enough to use the computer's time stamp. I also wouldn't be surprised if users had access to change the clock.

I've had an electric car since 2011. The battery looks like it will last another 10 years.

Early Nissan Leaf batteries degraded relatively quickly (8-10 years) due to poor battery chemistry and no thermal management. Both of these issues have been fixed in all new electric cars (except the new Nissan Leaf which still doesn't have battery cooling).

Even the old degraded batteries are valuable as static energy storage, and several people are using them as house batteries.

Most of the cost of a battery replacement is the manufacturer markup. There is at least one company making replacement Nissan Leaf batteries for significantly less than Nissan, and they include the latest chemistry and liquid cooling (unlike Nissan who just give you a second hand battery).

Most electric cars today have a 10 year warranty on the battery. Manufacturers wouldn't be offering that if there was a reasonable chance you would need to replace the battery in that time.

Autonomous vehicles work better on rails also without having to deal with pedestrians.
