Almost all diesel engines exceed official emissions limits once they are in the hands of motorists according to new research, as questions were yesterday raised about potential emissions rigging by Vauxhall and Renault.
Consumer magazine Which? found that 95pc of diesel cars and 10pc of petrol vehicles emitted nitrogen oxides (NOx) above acceptable levels when driven on public roads.
That’s the problem with emissions standards anyway. It’s like school exams, people teaching to the test. Set a standard and everyone will simply make sure that the test can be passed and damn the real world.
The actual answer is that if we decide we want to have cars at a particular price then we have to accept that some people will die.
Similarly, if we decide that we don’t want cars at those price points then also some people will die as a result of no transport.
What isn’t possible is that some people won’t die.
