We've all seen, heard and smelt this while drivers make deliveries, stop for refreshments, await the return of sight-seeing passengers and so on. Is there a technical reason, such as diesel engines being difficult to restart when warm?
If not, in the interests of their own financial well-being, together with the health of the passer-by and the environment, perhaps the operators could issue guidance to their drivers to switch off. It would be much appreciated.
