But without alternating case, how else are we supposed to denote SaRcAsM aNd MoCkErY??

I know I’m just talking to a troll, but I’m still going to take this opportunity to remind everyone that LBJ pissed off the white supremacist voters by signing the Civil Rights Act, and then Nixon immediately courted those same voters for his Presidential campaign.

if you don’t pass a driver’s test in the US, you might as well not exist

I don’t know how it is in other states, but here in Nebraska, you can get an ID card that’s pretty much the same as a DL for identification purposes. No need to fuss about with a driver’s test. Your ability to go anywhere is pretty much nonexistent, but that’s a completely different discussion.
