Tinted front windshields are illegal in California, among other states, fwiw. The law just isn’t enforced, just like modded exhaust, and residential speed limits … and passing on the right.
It's perfectly legal in California to safely pass on the right on a multilane highway and in some other situations. What is illegal is using anything other than a normal traffic lane to do this, such as the shoulder.
Of course this does not excuse GP's practice where "I regularly pass people on the right and then cut them off getting back into the left lane..."
Unless I misunderstood GP's comment, that sounds like reckless driving.

CVC 21754. The driver of a vehicle may overtake and pass to the right of another vehicle only under the following conditions: (c) Upon any highway outside of a business or residence district with unobstructed pavement of sufficient width and clearly marked for two or more lines of moving traffic in the direction of travel.
CVC 21755. (a) The driver of a vehicle may overtake and pass another vehicle upon the right only under conditions permitting that movement in safety. In no event shall that movement be made by driving off the paved or main-traveled portion of the roadway.

You were being pedantic up until here, so let's continue with the presumption of pedantry: what GP described is very far from reckless driving because they knew exactly what they were doing. You can cut people off safely, if dickishly, because of how the laws of physics work: cars can't suddenly teleport into where you will be, acceleration (especially at those speeds) is relatively slow for the vast majority of passenger vehicles.
I hate this so much around me in Massachusetts. Makes it impossible to know what the driver is going to do at an intersection when I can’t seem them. Often they resort to rolling down their window to be able to politely gesture at me, which would not be necessary if I could see them in the first place as should be legally required </rant>
