That’s a shame. Most of my journeys are 40 minutes and if this becomes £2 per journey (i.e. £4 per day) , then it’s getting close to the cost of using the tube. Might have to do some journey splitting now..
Simpler to use? This looks more like a revenue generation exercise to me. I bet 97% of the excess fares are for journeys between 31 and 60 minutes. Doubling the cost of going one minute over 30 is cynical rather than simple. TFL should extend the initial period to 45 minutes to compensate.
