"The South Carolina speed limits are absolute."
"There is no such thing as the 10 mph rule."
These two gems of wisdom were given to me by a good friend, who also happens to be a sheriff's deputy in Beaufort County. We were discussing, for example, the speed limit on U.S. 17, which I argued was too low at 45 mph. I usually drive this road at 50, thinking that the 5 mph buffer is OK, so long as I keep it within that flexible limit. Unfortunately, I frequently "flex" it to 55. Well, everybody else does it, don't they?
Sorry, but no such luck. The citizens of Ridgeland deserve to have their lives protected and made safer and anything they can do, within the law, to ensure this goal should not be restricted by state authorities. If anything should be done about it, those authorities should emulate such wise municipal planning. I-95 is a highway, not a racetrack. And there is nothing wrong with that revenue.
Realistically, the sheriff's deputies do understand the variable relationship between the human foot and the automobile accelerator, and are somewhat forgiving, within limits -- thus the myth of the 10 mph rule. However, knowledge and wisdom are free commodities and are universally available; therefore, their exercise should not be a serious problem for the driving public.
