The reality is that a semi-truck loaded up with produce is a bigger risk from the “turns my car into shrapnel in an crash” scenario.
Also, do you live in Germany or just near a bunch of extremely reckless and extremely wealthy drivers?
- blendo 7y agoI'm speaking from a California perspective, so yes, we have fair number of poor drivers. But I have NO concerns with Porsches on the Autobahn. In fact, I had a Porsche up to 270kph between Stuttgart and Karlsruhe once. Thrilling, but kind of terrifying (and I was a pretty well trained autocrosser back then).

- 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.
