@helge@mastodon.social @fmarini@mastodon.social @finestructure@mastodon.social Ok, from my perspective, >130 km/h (already over the speed limits here) is “going too fast”, hence most of my confusion. I can’t concede that going 130 is giving you so much more air resistance over 85 that you are getting worse fuel economy in any car even capable of going that fast comfortably, but its a totally different story for >200 😛 (Also, do I even want to know what an accident looks like at 200 km/h? 😬)

@dimitribouniol@mastodon.social You are absolutely getting worse fuel economy at 130 than at 85. Investigate, you've been giving all the information multiple times now. Look into how air resistance (or drag) scales with velocity. Consider why cars are shaped the way they are, especially cars that are designed to go fast.

@dimitribouniol@mastodon.social @fmarini@mastodon.social @finestructure@mastodon.social You seem to try to suggest that going with a car in Germany is more dangerous than elsewhere. Well it has 3.3 deaths per 100k in Germany while the US has over 14! https://en.wikipedia.org/wiki/List_of_countries_by_traffic-related_death_rate

@dimitribouniol@mastodon.social @helge@mastodon.social @finestructure@mastodon.social see my other response. I have a 2.0L, 275CV car that can quite easily go well over 200 km/h, and yeah, I get much worse fuel economy at 130 (and over) than at 85. And I can assure you it’s a really competent track car, so it *is* made to go fast, like really fast. Other less track ready cars might be more optimized for cruising at 100-130 km/h, but a lot are not, I’m quite sure 🤷🏼‍♂️
