When I wasnt able to work from home, I would have to get a train and a bus.
There was no direct link - train like to the wrong side of the city, then a bus through the city to the office.
The train and bus were absolutely rammed full during rush hour. The whole trip was around 2 hours.
If I drove, I could take the motorway directly and be there in 25-30 mins
Public transport is great until you have to take multiple hops on extremely busy, infrequently running services which arent even direct
