I realize that a lot of people here are privileged enough to own a single family home, but the majority of humanity lives in apartments and parks on the street. Trickle-charging at home is not a universal solution. The only practical solution seems to be some form of rapid charging of the car's energy storage. Either by pumping huge amounts of amps into a huge battery pack, or adding some kind of chemical fuel that gets reacted in an internal combustion engine or a fuel cell.

The Jeep hack (as well as their Toyota and Ford hacks) was exptremely important, because it put public pressure on the less technologically capable OEMs to get with the times and implement a (somewhat) secure electronics architecture. As someone who shares the road with those shitty cars I'm thankful for that. But even at the time of the hack, there were many OEMs whose cars were not anywhere close to that vulnerable and the industry hasn't stood still since then.

And since you mention Tesla, I also have to point out that they are one of the worst at security. E.g. they have an RJ45 port behind the dash that you can just plug into. It used to be that this gave you complete access to everything, but people abused it. So Tesla made it a little bit harder, though not impossible, to get into their system. Tesla also has a lot of bugs in their smartphone integration that allow "fun" exploits like remote unlocking.

Battleships only exist as mothballed reserves. A battleship was one of the largest ships in the fleet with massive guns and super thick armor. It was meant to fight in the major fleet vs. fleet battles. The name stems form "line of battle ship", because these ships were typically arrayed in a line starting back in the late middle ages. When WW2 showed that airplanes and missiles had made big guns and armor redundant, battleships were relegated to being giant anti-air plattforms that escorted the aircraft carriers. No one built any new ones since then, though "missile battleships" were studied for a while.

A massive step down in size are cruisers, who used to be ships that operated independently form the fleet. There are very few of those around nowadays and they tend to be the core of a fleet instead of cruising alone. You will often see them armed with hundreds of anti-ship missiles nowadays.

The next step down are destroyers, which are still fleet escorts (mostly against aircraft, hence Air Warfare Destroyer) in the major navies and have also taken up the role of going on independent operations. This is because smaller navies tend to not have any destroyers or bigger ships, so sending one destroyer armed with say 64 missiles can be sufficient. A destroyer used to be a relatively small ship that had the job of defending the fleet against other small ships like torpedoboats or submarines. The name stems from "torpedoboat destroyer".

The next smaller categories is frigates. These are the most numerous and are the workhorses of modern navies. They do convoy escort, but also defend bigger fleets from submarines. Many navies also send them on independent missions. They will tend to have 16 or 32 missiles, but won't typically have the big anti air radar a destroyer would. "Frigate" was the name used for sailing ships that couldn't stand in the line of battle. I.e. in say 1750 there would be only two categories: line'o'battleships and frigates.

Those categories are the major ocean-going combat ships. There are lots of smaller ships below that and a lot of support ships, too.

We have far less of an acceptance of plea bargains. Pre-trial deals are almost unheard of, because the defendent can "come clean" at any time of the trial and the timing must not enter the judgement to their detriment. OTOH a defendent also has nothing to gain from co-operating early beyond whatever he/she is absolutely required by law to do. This means that the prosecussion will almost always have to do the entire work of proving beyond any reasonable doubt that the accused is guilty. Which they have to do on paper long before the first hearing is held.

Hence, cases brought to trial in Germany are generally water-tight. Stadler is almost definitely going to prison. The only question is for how long and who else he implicates.
