"...received a speeding ticket in a stock Model A"?
Yeah, right...
(Brings new definition to the phrase "In your dreams.")
But not for the reason you might think. Here in California, if you boxed your Model A frame, filled it with mercury (or whatever bootleggers used), got a running start downhill with a tailwind and tried flat out, you'd still be passed by everyone else, whether on a residential street, highway or freeway, including by the local police/sheriff/highway patrol. Around here, speed limit signs are viewed as the minimum allowable speed, and the center divider just establishes who has responsibility for running pedestrians back onto the sidewalk.
But, you gotta love it; life on the edge. And good weather to boot...
