Exaggeration is not exactly lying, it is a way to help make your point, to help convince.
So Husker writes of being 100% safe, which nothing ever is, even if there were no cars in sight, no cars parked on the street, no residences nearby. What I did was seen by zerobody (except the gent in the black and white). Husker also characterized my two feet of back end slide as "drifting".
The exaggerations by the policeman are a clue to his motive for not giving me any ticket. When he listed the offences he could have charged me with (usually a negotiating tactic to get you to accept a lesser charge without making a fuss) he mentioned "reckless endangerment," which it clearly wasn't since there was no one to endanger. And he mentioned "driving like a teenager" twice. But I wasn't careening about the streets; I came to a full stops at the line three times, looked carefully then pulled my off-the-line stunt turns. He saw that as clearly as my offences.
I think (and it is only speculation about what went on in somebody else's head) that he considered it "responsible hot-rodding" and liked that an old guy could have fun with his hot car and still be safe.
