My wife is IT geek for a large ready-mix concrete operation, and she was telling me about the presentation she sat in on for a truck tracking package that collects an amazing array of data on each truck in the field and transmits it to HQ in real time. These mixer trucks obviously have a high center of gravity and are prone to tipping. The software records the truck's lateral acceleration in turns, so big brother can see if drivers are likely to tip their trucks. My wife noted that 0.23 g's of lateral acceleration will tip a cement mixer truck. Compare that to skidpad performance of .85 or so for a good sporty car and about 1.0 for the best sports cars, on street tires, anyway. These skidpad figures are measures of the point at which the car slides into or out of the turn, not when it tips over, fortunately!
