Absolutely not true. I don't know what the Tesla's speedometer display is like, but my experience with digital displays in cars is the exact opposite. I am much more likely to misread a digital display - in my old car this happened all the time with the digital clock display in the dash. I've never owned a car with a digital-only speedometer, but I've never liked them in rental cars.
Digital displays are obviously better for reading a precise value, but not necessarily an accurate one. To generalize, I would say being off by a a couple percent is more likely when reading an analog display, but off by a factor of two is more likely by misreading a digital one.
