We're all in a hurry...
And the nice autonomous driving vehicles we all want rarely take this into account. Having just driven around 600 miles two days ago (coming back from the eclipse watching), I saw lots of people just doing bad things. Yes, there were all types and then you mix up trucks (aka lorries) on the road that desire to pass one another at speeds about 10 mph below passenger cars, you get frustrated. Compound that with cranky passengers that demand food/drink/rest stops NOW, and you get an interesting mix of conditions.
Autonomous driving hasn't come here yet, so we must drive ourselves around and go long distances. I challenge Elon and Company to get his nice electric vehicle from here in Sillycon Valley to greater LA all by itself. The distance is around 300 miles, and (thankfully) I can get that on a single tank of gas (petrol) in my big ugly SUV that I drive. It takes around 5 - 6 hours (traffic on I-5) but it can be done.
Yes, warning systems are nice, but educating drivers is a good start. Remember:
"Ban low performance drivers, not high performance cars"!
