> Until you do the math and realize that the 3-4 annual trips of multiple days would end up costing thousands of dollars in rental fees per year.

First, 3-4 annual multi-day trips that go for longer than 300 km? If one has that amount of disposable income to afford that, go for whatever the biggest Tesla is and use Superchargers along the route, even drives so long they're a safety issue on its own due to fatigue don't get that much longer due to charging because kids will need to go to the toilet every so often even with an ICE.

As for the rental fees: here in Germany, I just checked - a Mercedes Benz Vito, so up to 8 people (or 6 people plus a ton of luggage), that's 50€ a day here. Crossing four digits takes 20 days of rental, that's a lot of vacation time even by European standards.

I'm surprised you consider a 300km trip long, or 3-4 trips in a year excessive. That's only Berlin to Bielefeld. What do you do with your holiday?

The EU minimum is 20 days annual leave per year.
