I wouldn't call them "worst scum" as much as idealistic to the point of destruction... most often of the innocent. They're a clear speed bump to progress, but not as bad as some problems in the long run.
We don't need to KILL them, but they do need much more effective regulation. The Bar just doesn't cut it these days. That and highly regulate the number practicing at any one time. The US alone graduates and licenses more lawyers than there is work for, and that's precisely why we see the shenanigans we do, like Prenda. Lawyers who would otherwise be unemployed game the system to earn a living. The oversaturation of lawyers is the root cause of most modern ails - look close enough at any problem and you'll find a passel of lawyers trying to make a buck (or a million).
I happily bought Psygnosis games for the Amiga because they came with extras - a poster and a T-shirt was standard, and sometimes they'd have a couple other items. It didn't add to the price of the game, either. Games came on cheap floppy disks, and retailers wanted a BIG box to discourage shoplifting, so you normally had one or two floppies in a big empty box. Pysgnosis at least filled that box a bit with cheap stuff that appealed to the market - a big poster and a t-shirt.
Um - iffen I were on a road like that, I'd NOT get on a road like that. I'd find another route, even iffen it were twice as long. Half of safe driving is planning routes that aren't virtual suicide. Need to make a left turn at an intersection where a dozen people are killed turning left every year? DON'T! Go a couple blocks further down where you have a protected left turn and they've only killed one person in the last decade.
If you did find yourself in such a situation, clearly the best thing to do is keep your speed at a level where you can see, but not so low as to get rear-ended, and to pull off at the VERY FIRST place to do so. It's not perfect, but like you point out, you sometimes find yourself in imperfect situations.
If your choices are plow into a baby carriage "suddenly" appearing in the road or plow into a crowded sidewalk, you were GOING TO FAST FOR CONDITIONS. Always drive at a speed where you can deal with "sudden" changes in the roadway. Example, DON'T TAILGATE A PICKUP WITH POORLY TIED DOWN FURNITURE. Stay back far enough that you can safely change lanes when something falls out. "But then five cars will pull in ahead of me!" Good! Let them run into the furniture while you stay safe. God! People have the stupidest responses to safe driving practices... that's why we kill more people with cars than any other way.
No it's not. You ALWAYS have the pull off the road option. ALWAYS. You just choose not to use it and blindly drive through the fog hoping for the best. And most of the time you're right! And once in a while, you're part of a sixty car pile-up with a dozen people dead.
I taught driver's ed and defensive driving for many years, and things like the Trolley Problem are errors people made long before that are easily avoided if you think about it. An example I loved to give classes: You're driving to work in the morning and run into a bank of thick fog. Do you a) slow down and get rear ended by someone behind who isn't going to slow down, or do you b) maintain your speed and hope there's nothing ahead of you? The correct answer is c) don't drive through the fog. Get off the freeway onto a surface street where you can go slow through the fog without getting rear ended, or d) pull of the road (maybe at a Dunkin Donuts) and wait out the fog, or e) realize the fog occurs every damn morning this time of year and leave early before it forms. See, being caught in the fog and having to make a life or death decision means you blew it LONG before you ever got to the fog, and that there are many more answers than kill yourself or kill others.
