I actually did borrow my parents car because the commute got so bad. I commute from Aachen to Cologne. After 2 trips there and back which would usually take me about 4 hours total, I had accumulated over 8 hours of total travel time and kinda had enough. Was very glad i was able to WFH.
Huh, why did the 9 Euro ticket double your travel time? Did the trains get slower? Did they cancel the fast trains? Were the trains so full you had to wait 2 hours to find space in one?
