Its not for blind drivers and it's not braille.
If u know touch typing u will know what it is right away but since all of u don't I won't say what they're for.
If u know touch typing than u will know it's just there so that u can feel where the horn is so u can hit it without looking
And in touch typing the f and j keys have bumps on them too so u can find where all the keys are from that
You missed the entire point of the meme. The meme was that the image pointing out those bumps mention said that they were for blind drivers. Blind driving is illegal.
You literally responded with r/woosh when I got the joke. The point of the meme went right over your head. That's why I replied to your comment with woosh. And I explained the meme to you.
When you started the thread, you said that the joke was good. But, later on in the thread, you said that it wasn't funny. It seems you said "Good joke." just to be polite.
