Kinetic energy rises with the square of velocity... and the Porsche is much more likely to be driving unsafely/like an ass than the truck, or in my experience, even a BMW...
- dpark 7y ago> Kinetic energy rises with the square of velocity That's all well and good but a fully-loaded semi-truck weighs 15x as much as a full-loaded Taycan. My rough calculations say a fully-loaded Taycan driving 150 mph has a kinetic energy of 6.5 MJ while a fully loaded (80 thousand pound) semi at 80mph has a kinetic energy of 23 MJ. In fact a semi at 45 mph still has (slightly) more kinetic energy than a Taycan at 150. I wasn't very good at physics so maybe I screwed this up. But yes, the Porsche driving 150 is more likely to fly across a median to hit your family sedan head-on.
