A gallon is 3.785 litres, and the euro is roughly $1.05.
So 2 euros per litre = one gallon costs $8.
A US liquid gallon is defined as 3.785411784 liters, the US dry gallon is 4.40488377086 liters, while the imperial gallon is 4.54609 liters. And that's just the currently used definitions...
If I ask Google for "1 gallon in liters", it assumes Imperial gallons which would account for a good chunk of the error.
That's not true at all. There's lots of direct service to notable destinations. It's rather if you want to go to un-notable destinations (which is of course something that people do a lot in their daily lives) that you can expect to have to transfer.
Wow. Things must have improved incredibly in the last ten years.
Better data: https://de.statista.com/infografik/13644/laenge-von-arbeitsw... Can't find how to change the language, even though it's an international page. The graph shows minutes per single way. The pie diagram seems to be a popular vote on "maximum acceptable time".
Public transport is pretty good on this connection, but overall it takes me 75-90 mins, because I need to change twice and there are wait times.
° Well, I'm working from home now...
I used to live in a different, larger, city, and worked on the opposite side of the same city. Distance 13km. Driving commute 30 mins (middle of the night) to 45 mins (rush hour) each way. Public transport 90 mins...
Edit: As a student I pay 90€ for a "semester ticket" once every 6 months.
