35% of trips in Darmstadt are done with a car, that means 65% are not. Parking is a horrible indicator for that. No, in the snippet you linked it says that in 2018 35% of trips within Darmstadt (length = 1-3km) were done by car. 3 km being walking distance for I think this is quite high. I’m sure however that the current number is lower. For some reason you assume that people living near center never leave it - your attempt at straw manning the Parking into this leads me to assume you’re just being disingenuous (again).

Let’s still run with it and look at the source of your outdated and ill-interpreted snippet. The current version is covering all cities and the result presentation differs a bit: Ergebnispräsentation SrV 2023. Download the PDF and look at the following slides. slides:

• 12 - Modal Split (aufkommensbezogen) <- i.e. moste frequently used by type
• 13 - Modal Split (verkehrsleistungsbezogen) <- i.e. length by type
• 30 - Antriebsarten der Pkw nach Raumtyp
• 31 - Comparison of charging options by area type
• 36 - length of e|bike trips by area type

What you should see looking at these:

• cars are used for only a third of trips / P
• cars are used for 57,5% of total length travelled / P
  • this paired with TCO of a car vs. rental cost is one reason for the parking situation we can observe
• bikes are used for a trip length up to 5km (avg)
• EV usage, while growing, is not where it needs to be.
• EV usage in big cities is lower than in small cities (re-read this thread to discover why that is)
• urban regions have a higher usage and demand for public charging (this, with the point above should hopefully rase some questions )

.

Also Germany has a lot of suburbanization happening. It is not quite American style, but it is pretty easy to find parts of cities with nearly exlcusivly single family houses. The street layout is better, they do have some public transport and are denser, but they are nonetheless suburbs. For Darmstadt Wixhausen is a pretty good example of a suburb.

Honestly, this might be the dumbest thing I have read today. Yes, Wixhausen is one of the suburbs of Darmstadt. In fact most if not all cities on the planet have suburbs. No, they are not all the same and Wixhausen is nothing like US suburbs.
