Driving cross country in a car is actually the worst when you're in stop and go traffic, or cars keep slowing down and then speeding up. I can't wait to get my hands on adaptive cruise control because I get so aggravated and tired from having to shift and adjust speed. If I can just sit in one position and listen to comedy podcasts and audio books I do so much better

I finally got a car with adaptive cruise control and lane assist a couple of years ago. It is the best. Driving feels relaxing. I actually feel less fatigued. I can just listen to music /podcasts /audiobooks and not care about how others are driving. Feels like sitting in the passenger seat and watching the road. I wouldn't feel safe if I wasn't listening to something that kept me engaged though. I would totally nod…

I don’t have good “lane centering” but knowing that it has the lane departure warning and will automatically bounce me back into the lane if I slip up for a moment is enough to make driving less stressful.

I was excited to get adaptive cruise control, but I’ve found I don’t like using it very much. It’s too aggressive with hitting the breaks to maintain the following distance instead of being able to ease off the gas to fall back like a human driver would. Assume some brands are better at this than others, but anyway I didn’t buy a Mazda to not drive it. So I use that only intermittently for long drives as a bit of a break for my right foot.

We passed an aircraft carrier going up the East Coast while they were doing exercises. They radioed us and made it clear not to come close to the ship. I have video of fighter jets doing low passes over our yacht every 15 minutes or so using us as a practice target. Going South once, as we came towards the inlet at Fernandina Beach on the Florida, Georgia line, a nuclear submarine was leaving port. I was at the helm…

This is all very interesting and completely foreign to me! > Coast Guard helicopter with a mounted machine gun pointed at me and a Coast Guard response (defender class) boat with a .50-caliber machine gun also fixed on me while they sat off our bow. Why'd they do that? > they said I should hold my position and not move. Why? > The sub came out with two large ships on each side with blast shields on the each ship. ...…

I have be boarded by Coast Guard while entering US territorial waters. They will line up all boats moving from Bahamas towards Florida and have them hold speed and direction. Then they push an inflatable boat onto the stern and board with about 6 people all armed with fully automatic rifles. Mostly, they look under the floor boards for drugs and make sure the registration and documents are correct. The Coast Guard does not mess around.

When a $2,000,000,000 Ohio class submarine carrying ballistic missiles is most vulnerable leaving port moving towards water deep enough to dive in. The Coast Guard is tasked with keeping all potential threats away. The ships on the side would protect the submarine from RPG and similar attacks while the submarine is surfaced.

I don't know about in other countries, but commercial pilots in India have random daily schedules - for example, today the flying time could be 1 pm to 8 pm, tomorrow it could be 8 pm to 3 am, then two days later it could be 2 am to 9 am. Given how random the timings are, I'm not surprised about captains falling asleep (maybe not first officers, who are younger (saying this out of hearing an anecdote about this)).

> deadman switches Seems like they could address this by just changing procedures. If one pilot wants to take a nap, require a third crew member to come sit in the cockpit and make sure the other pilot doesn't doze off. When two pilots are awake, they can monitor each other, but if one is (intentionally) asleep, they can't do that, so have someone take over that function.

Procedures don't work well when people are incentivized to violate them. Confessing to sleeping on the job is a career threatening move.

I'm not a pilot, but it seems like in some cases (depending on who sets the rules), it's allowed.

Each pilot can have a button they must always press, if both are released loud tritones alarms and flashing will fill the cockpit, something no one can sleep to.

Well... You can. Sleep deprivation is one hell of a drug. After ~23h on a plane without sleep, I slept through a fire alarm at a hotel. It's unlikely that both pilots and other staff would ignore it, but "no one can sleep to" threshold is not that low.

Have the alarm go off in the cabin as well.
