I travel about 15 miles a day, each way, on the bus. I get a 10-trip ticket, works out at £2.20 each way. I calculate driving costs 30p per mile (and yes, you have to include the cost of the tax, insurance etc. because you don’t get that for free and I don’t agree with the reasoning that they’re fixed costs) hence about £4.50 each way. Plus I don’t get free parking so that’s £5 per day.
Realistically, driving would cost me £14 per day – at best, if I could get free parking and ignored the running costs, it would cost £5 in fuel. Bus costs £4.40 per day. Cracking value if you ask me.
And I do cycle it sometimes, before you ask. It allowed me to justify a +1 for the collection.
