You and your logic. Damn you!

A 33-1/3 RPM record turns 33-1/3 RPMs at the center and at the outer perimeter. It’s a solid disk. If you draw a straight line from the center to the edge and put it on a turntable at the speed given above, it will take the same amount of time for the mark to come full circle at the center as it does for the mark to come full circle at the outer edge. The centrifugal force at the outer edge will be greater, though; because more distance is being covered at the outer edge at that speed than is being covered near the center. The turntable speed does not change with the position of the needle on the platter (record). The VW bus, on the other hand, is the object that is moving instead of the record itself; so the speed of the bus would have to vary in order to mimic the playback speed of the record.

What say ye?

Think, maan, think!
Record playing speed on the turntable is constant, so is the bus!

I’m so skeptic about it though I can say is that it is a portable vinyl player hehehe.

Don’t you think the bus can change his own speed with time passing?

They just need to put in a timer wich reset when you start the engine…

Precise turning radius? The radius changes with every rotation. Speed? Every lap has a different length. That means that both the speed and turning radius are not constants.

I have doubts that this would perform as advertised.
