"Shock in cars is ameliorated by buffering the data, everybody and his brother knows that. "Ok, guys. I do not know much about intricacies of CD reproduction, but have had a car and a CD player.
Some car CD players were advertised as having ESP or some sort of it. A buffer of sorts. When same brand had different models, those higher ones were advertised as having an advantage because of ESP.
Relatively early, I tried comparing such models and those without ESP did skip more over proper potholes.
At some point, I was looking for a CD player for a car and was to skip a certain model because it did not have ESP. Salesperson said I should have not been worried as isolation, or whatever, was improved enough in then-newer models that I would not notice the difference between ESP and non-ESP. He was right. I managed to make that particular CD player skip on purpose. One bump, a proper one, and not a series of them as would be needed for ESP. Without that deliberate insult, the thing skips once a decade, I think. Which is quite a feat.
No, geoffkait, you are not right and if you followed my advice and have known when to stop you would have not assumed I wished I had shut my mouth.
