Funny because of the self destruct party but I agree driver training needs to be more rigorous.
Having done autocross, I honestly believe people would be better drivers if they better understood their vehicles at the limits of handling
I disagree. The problem is not that people don't understand their vehicle (they don't. It is just not the problem) it is that they are doing so many other things other then driving that vehicle while it is in motion. Consider trying to drive Autocross while eating a sandwich and reading your email. That is how most drivers do.
When you fail at that it will not be because you didn't understand your vehicle well enough.
Understanding the limits can't hurt, and distracted driving is also a huge problem which is why I joked about shock therapy, but it is much more than either of those for me. Possible long post incoming:
The first thing drivers need to understand is that the moment you get behind the wheel, even if you drive perfectly, you are a fucking annoyance to everyone else on the road. Your very presence makes every other driver that passes within LOS worse. Everyone wishes they had the entire road system to themselves, and you are spoiling that experience.
With that in mind, you can now understand why road rage happens. If you are not driving with that mindset, that you have a duty to not inconvenience other drivers any more than absolutely necessary, then you are going to increase negative emotions on the road exponentially with every seemingly minor fuck-up.
Now, it's easy to say "people should control their emotions," but humans are inherently emotional creatures, and on the road it would be much better for people to be able to focus on their own driving without also having to focus on and process someone else's shitty driving. Simply put, if you are adding unnecessary inconvenience to the system, then you are a nuisance and should not be allowed to drive. Period.
Let's look at a simple example to illustrate the type of person that should not be allowed to drive. Speed limits are calibrated for the dumbest motherfuckers on the road. They have to be. If you've ever driven the speed limit and thought to yourself "this seems appropriate, anything much faster and it would be difficult to control my vehicle on this road," you should sell your car immediately and launch your DL into the sun. Your absolute highest priority should be changing whatever you need to change in your life so that you can rely on public transportation or at least someone else to drive your ass where you need to go. Driving the speed limit is fucking painful to competent drivers, let alone above average drivers. A competent driver could build a Lego Death Star while simultaneously driving the speed limit if they had to.
Please do not get me wrong, I'm not advocating that we should all be street racing. People weaving in and out of traffic are a fucking nuisance as well. But we all have to suffer ridiculous speed limits simply because we as a society have decided that everyone should have the right to drive if they can do so without shitting their pants in the process more than once per trip, and have decided that all the deaths and dismemberment this causes is just acceptable.
I'll stop now because I could go on for hours...
