There has been great exhortations from politicians and environmentalists about diesel cars and the damage they do. However, ask a taxi driver and he will assure you that such vehicles cover greater miles, are more robust and with sufficient filtering can be as environmental as petrol. The article below from the Times seems to support this. However, UK automotive dealers, fleet holders and funders are expecting a sharp drop off in value against the nearly new range of diesels. Despite this we are a long way from electric vehicles and the harvesting of precious metals and the production of long life batteries has its own issues. In the interim it is likely that the UK automotive industry will be mindful of further regulation in this field. One wonders were it not for recent scandals about emissions and their authenticity, such scrutiny, may not have occurred at such a pace.
