I doubt he drives anymore, because so many things scare him and I would expect the act of being in control of a big metal box with an engine surrounded by other such objects to be one of those things. Dude can't even talk to people.
Since he started wearing the gunner glasses, I've ceased thinking that his refusal to put on any that help him see is out of fear of the jokes, since honestly it has to be more irksome to him that we meme about him playing dress up for shekels like a cam whore.
No, I'm now pretty sure it's about the fact that if he wore corrective lenses, it would mean admitting that people are right to tell him to, and we know how he is about other people being right. It obviously applies to more than just detractors, since I've never seen any photos or footage of him wearing corrective lenses, and I seriously doubt his poor vision has only caused him problems while playing video games. He has had comments about needing glasses most of his life, and as he admitted to yesterday, he's one of those motherfuckers you can't tell nothing to.
Basically, he doesn't wear them because he loves being spiteful as much he loves being lazy.
Learning about shit like that is what prompted me to go from "Phil is a dumbass who knows not what he does" to "Phil is a scumbag who enjoys getting away with sleazy shit and lies as easily as he breathes".
