It wasn't intended as bragging. Just a wry, self-mocking reflection on the irony of the situation. But I suppose that wouldn't be apparent unless you knew me or I said it face to face. Speeding's nothing to brag about, I'm a bit too old for that. Plus I hate burning petrol.
Bragging about speeding is a bit more pistonheads than lufuguss though. You'd think we'd know all about travelling without brakes, mind you.
