I've noticed a lot of people being more comfortable being hateful. I'm around women more so I notice it more in women.

Yup. People are way more comfortable being antisocial and nasty.

As for pickup truck drivers—most of them are not psychologically fit to be on the road.

I've noticed an insane amount of reckless and aggressive driving since covid. Doesn't seem to matter if the driver is male or female, old or young, new car or old car, if my husband is driving or if I am, or even the location. Definitely more people tailgating me, aggressively speeding and weaving through traffic, and just blatantly running red lights.

I think lots of people got more aggressive, impatient, and angry after covid lockdowns ended. I can imagine that a lot of those same people are comfortable now with getting even more aggressive, especially those men against women.

There is research about Covid related brain damage and how it might help explain some of the increase in bad driving and aggression. It's not the only reason, but it is something that many people won't think about, but there is research about this and some warnings about driver performance after Covid emerged.
