I say everyone should drive like they are drunk and stoned- but do neither while driving at least (on public roads.) Go slower, but not too slow, be paranoid about hazards or cops around, but be bold enough to not jerk the wheel or freak out by some headlights.
Everyone should, really, drive like an illegal. Not the way they ACTUALLY do (thank you kind sirs 2X but thankfully I have uninsured rider on my policy so I was covered) but how the illegals SHOULD if they were rational, have another criminal warrant on them, and not drunk:
Pretend, when driving, that you live in one of the few states who cares about it and you are an illegal,-- you have no license, you have no insurance, and you have no inspection sticker or registration so you are a sitting duck for a cops that cares. And that redneck cop is going to wring your neck if caught and then send you back to old Mexico. In other words: drive at appropriate speeds, keep eyes moving and being alert to any danger, switch lanes appropriately, and obey traffic signs.
Or pretend to be a spy in some foreign locale. Keep an eye on everything, front, back center, who is following, what turn can I make to get out of here, have I seen that car before, am I boxed in, are these one-way streets if I need to cut off, etc.
You will be a better driver and it makes it a fun game!
