I'm on the line about whether or not the bus is cheaper than driving or quicker than taking the bike, but it is sheltered and involves no parking or finding somewhere to leave the trailer. At the moment dd is free on the bus, once she turns 5 driving will definitely be cheaper. SLightly o/t, I want to raise her to be able to get herself around by bus/bike/walking, so in some ways we'll just have to swallow the extra cost.

I do find it difficult to quantify the various costs. With a car that is all paid for and ready to use there is the temptation just to use it anyway, to get the best return on investment. But short journeys damage the car and result in higher repair bills, and then there are the hidden benefits of the improvement to my health, modelling alternative transport to my daughter, and the hidden costs to the environment for journeys where I personally have access to alternative transport modes (bike, bus, feet).

Does your bike feel better for the improvements?
