Always Check Out Your Assumptions.
I chose to travel to and from the hospital in Málaga by public transport, not because I love buses per se, but because it is clearly so much cheaper than driving; or so I thought. Wednesday, I was going by car anyway and I switched on my satnav, as much to recharge the battery as anything. However, as I had entered the details into its system of the urban and rural fuel consumption as declared in my car’s owners’ manual, and the current price of diesel down here, the machine quietly monitored the distance travelled and worked out the round trip journey cost. It was an eye-opener. Firstly, the actual distance is slightly less than I had allowed for, but more importantly, I use a lot less fuel than I imagined. The result? It cost me 9.60€ in fuel and 2.30€ for the car park, so let’s call it 12€ in total. By bus, as I also have to get a snack in Málaga, it sets me back about 14.50€, and indeed, 4 or 5 euros more if I have to get a taxi back down to the bus station to be sure of making it in time to catch the 5 o’clock bus. So armed with that information, I have switched my strategy; henceforth, I shall drive to the hospital except when I can’t be bothered to do so. Only then will I go to the expense of the bus. Not only will I save money, I save time too. Public transport soaks up seven and a half hours of my day. Driving takes only three hours including the time at the hospital.
