Evo za brzinu je objasnjeno zasto dolazi do razlike: "The vehicle speed displayed in Channel 16 is not extremely accurate, despite its digital display. It basically serves to regulate the amount of fresh air intake in proportion to the vehicle speed – no mor and no less. [ed: After comparing with my GPS speed, I’ve found the channel 16 speed on my car to read closer to actual than the speedometer, but it tends to err one or two mph slower than actual... use as a speedo at your own risk.]"
Dakle on sluzi da regulishe kolicinu svezeg vazduha srazmjerno brzini kojom se krecemo. I izgleda da je stvarno malo tacniji nego cajger.
