I think the bigger savings will come in being able to precisely control stops, starts, and turning, which will both minimize damage to the road surface and lengthen tire life. ISTR a case where a large open pit mine bought GPS-driven trucks and saved a great deal just from longer tire life (each tire was $20K).
