Taxi Memes

The "ps" in the meme refers to picoseconds—one trillionth of a second. So this taxi driver is feeling superior about outliving you by an utterly insignificant amount of time that no human could possibly perceive. It's like bragging about having one more grain of sand at the beach. Physicists measure particle lifetimes in picoseconds, but taxi drivers? They're lucky if they can measure the optimal route to the airport.
