Quite often the people who do the most miles are running small businesses.
Everyone does, it’d all even out. All your competitors would have the same problem, costs would move about. It’s the only logical explanation both from a equality point of view (I for example pay full road tax on two cars and yet ride 6000 cycle commuting miles a year – It’s not fair!!), and from an ecological point of view people will have to reconsider the way they do things. If fuel is a pony a gallon, riding down the local grocer with a trailer on your bike seems perfectly acceptable.
We HAVE to get on top of our fuel consumption. Raising fuel costs is the only way. That will necessitate different approaches to business, people will use local firms rather than great big ones, you’ll not have to drive about so much, my business which operates over a huge geographical area will need to localise resources thus providing employment to some deprived areas, it’ll all be for the best.
