There's a saying, "ya can't fix stupid!" And, that is where we're at with 99% of drivers today, they're too stupid to know what they're doing, let alone even remotely being able to operate a motorized vehicle.
I've so enjoyed the past few months with the lack of drivers out on the roads (I'm an essential, I have to be out there). Last Friday it seems we're back to normal with the number of idiots on the road, doing what idiots do best.

I was driving down the street when one of these mental midgets on a scooter literally cuts me off! There was no reason for him to get into my lane, no one was in front of him for at least a quarter mile. After slowing me down, he decided he needed the other lane again and got back over. This is just one of at least a dozen incidences in that single day out!
On a good day, I can laugh off most of it . . . Last Friday wasn't one of those days!

There was another similar thread a week or so ago that I haven't re-found yet that was complaining about Prius and BMW drivers. Unfortunately, none of the stereotypes hold true anymore. There is no age, race, vehicle type, etc., that you can "shoehorn" any segment of bad driver into anymore. You're literally taking your life into your own hands when you go out there.
Never assume that anyone else knows how to drive. Don't assume that they're going to stop at a stop sign or red light. Don't assume that they're going to yeild the right of way. Don't assume anything. Wait until you're certain that they're doing as you expect before proceeding accordingly.
