"Is Flooring a Tesla on the Autobahn Actually Optimal?" — I vibecoded an app to find out (Germans will understand)

I kept wondering while cruising the Autobahn: if I floor it at 250 km/h in my Tesla, do I really arrive earlier or just end up charging more often? So I built a little **Ideal EV Route Calculator** that lets you plug in your Tesla model, set some chargers on the way, and it spits out the optimal combo of speed + charging stops to get to your destination as fast as possible. The answer surprised me: if you have enough chargers, you should probably go flat out and charge more often. [For example](https://ev-router.mdressler.dev/?m=Model+S&v=Plaid&sp=100&td=1000&ap=10&xs=322&ns=60&ck=250&cm=2256&wt=0&pt=0&st=100%3A0%3A250%2C200%3A0%3A250%2C300%3A0%3A250%2C400%3A0%3A250%2C500%3A0%3A250%2C600%3A0%3A250%2C700%3A0%3A250%2C800%3A0%3A250%2C900%3A0%3A250), on a 1000km route with V3 superchargers every 100km, you skip charger 1 and barrel down straight to charger 2 at 251 km/h and then keep hopping to the next one at 238 km/h until you arrived (Model S Plaid). The simplified reason: while you lose energy four times as much at 270 km/h (\~152 kW) as at 135 km/h, you still charge a lot faster at 250kW superchargers. You can play with different optimization goals like time-saving vs. drive-saving and battery protection vs. raw speed to get a feel for the ideal driving style for your most common routes. >Disclaimer: I trust the math.
