If there is something I have noticed living here in London over the past six months, it is the number of four wheel drives around. For some reason, it really pisses me off. People use big, heavy-duty machines, originally intended for exploring the Canadian wildernesses or the Australian outback, for the school run or daily commute. It’s silly: I know that they probably feel safer being so high up, but lord knows what impact such machines are having on the environment or the state of the roads. If you need a bigger vehicle for, say, lugging a wheelchair or two about, I can understand that; but surely not everyone needs one.
