Did you know that it's not safe to type a text message whilst driving? Well, just in case you didn't, some fool thought it would be a good idea to spend good money on a flipping study saying so.
There's a superb bit of drollery on this front over at the New Yorker, where Drew Dernavich contemplates other things you shouldn't do whilst driving, such as, inter alia,
Writing diary entries. Not because it’s dangerous, but because if you’re really honest with yourself, you’ll write “I’m just writing some thoughts while I’m driving…” and then later on, when somebody reads it, you’ll probably get arrested
Playing the accordion
Driving a second automobile
Whilst safe things to do whilst driving include, inter alia,
Putting icing on a birthday cake, because nobody pays any attention to what the icing looks like, plus it’s usually that disgusting sugary stuff, and it’s better to scrape it off and just eat the moist cake part
Planning the seating chart for your wedding, because you just put Uncle Louis anywhere, and he’s good, as long as it’s an open bar
Go read the whole thing. You'll love it.
