- Cthulhu_ 1y agoThat's actually a legal requirement (had to google some to get the source): [0].

- kuratkull 1y agoThe graph seems a bit too much. It says that GPS 110 means ~125 on the odo. Although from personal experience I'd say it's more around a delta of 5 at those speeds, and 3 for lower speeds.
- detaro 1y agoit has to fall somewhere in the shaded area. So if it shows 125, then the actual speed must be between 125 and 110 at worst.
