So I'm a recent convert from bmws.... I can't believe what ur saying is true as bmws have had this fixed since early eighties. In most modern cars the speed sensor is in the primary differential. I have a hard time believing in a car with all this technology the is250 doesnt have the same setup. The sensor monitors the rotation of the diff gears tracking the correct mileage and speed based on the rate of rotation of the drive train. So where is the speedo sensor on an is250?

BWM is different, they have the ability to input the rev/mile and stuff to correct the spedo from what my co-worker has told me (he owns an M3).
The Lexus vehicle does not have the ability to to reprogram the speed sensors.
The engineers at Lexus at programmed it such that the spedometer will always report accurate speed or above but never below your actual speed, assuming the proper tires are used.
This is what it would be.
