Speedo correction 2010 TDI Jetta

The thickness of the needle viewed from the angle will make you believe that you still doing for example 80km/h when in reality, it would be almost 90km/h.
So, the common sense is telling me that, if I don't seat absolutely 90 deg above the speedo needle, then it must display a greater speed than the car is traveling.

The Mavericks explanation why is there an error in displayed speed is spot on and similar to the official VW explanation. That's another example how is the VW helping you to save money - you don't get caught speeding as often, especially if you're the creeper.

Slight difference between the two in how they measure their speed, large aircraft don't rely on round rubber objects that change size to provide their speed, the tolerances and maintenance in planes is completely different to mass produced cars and the training between a pilot and a driver is dramatically different. Knowing the true speed of a plane is a hell of lot more important as well especially when you can't easily judge speed like you can in a car.

Maverick, I'm quite well aware of the differences between the two. But, getting an accurate speed from a car is a very simple exercise, and in this case it is completely frustrated by some level of bloody mindedness. I do not want VW, or any other maker removing about 10% of the speed that I am legally allowed to do, just because they feel like it. The speed limits in this country are anal enough, without them helping the situation.

And, it makes it doubly laughable, when you test drive something like a BMW X5 4d. Very nicely presented speed head up display, that is totally wrong. My Toyota Hilux had an accurate speedo. It isn't hard.
