Bad driving is worse than city’s 20mph speed limits

First published in Letters

It is a common myth that 20mph limits increase pollution (Argus, Aug 25).

The effects of slower speeds on vehicle emissions are likely to be mixed and we shouldn’t assume 20mph will be detrimental to local air quality.

Lower limits in urban areas may not have a significant influence on emissions of NOx and CO2,but emissions of particulates will probably decrease at 20mph compared with 30mph.

The main impact on levels of pollution probably comes from different approaches to acceleration and changing gear. The Dept for Transport’s own guidance in Circular 01/2013 says there may be environmental benefits from 20mph “as generally, driving more slowly at a steady pace will save fuel and carbon dioxide emissions, unless an unnecessarily low gear is used”.

So the role of driver behaviour in all of this is crucial.

The majority of drivers will adapt their behaviour because they accept the all-round benefits of less aggressive driving and cutting their speed.

It is only a small, stubborn minority who will refuse to change at all.

As well as the environmental impact of their aggressive behaviour, they will continue to put vulnerable road users at completely unnecessary risk from their speeding, discourage people from being more active, reduce enjoyment of public spaces and, ultimately, impose heavy burdens on all taxpayers.

A lower speed limit doesn't harm people – incompetent driving does.

I don't consider myself or the majority of other drivers who refuse to adhere to the ridiculous 20mph limits to be aggressive. I note that the few writers on here that support the 20mph limits like to use the word 'aggressive' when referring to us drivers who refuse to drive so slowly. I feel this is strange especially when these commenters no doubt were driving at faster speeds just a short while ago. Why are we aggressive when many of us are driving at speeds that we have been driving at for many years? How come we are suddenly aggressive?

As for bad driving, I have noticed several people who stick to the 20mph limits also seem to think it's ok to use their mobile phones while driving. Maybe they think that now they are driving slower, using their phones while driving is safe? And my pet hate...people who cannot be bothered to use their indicators. This seems to happen all too frequently now.

Since the change of the speed limits has not changed the actual speeds encountered on the roads, there will be no correlating change in pollution; unlike the myriad of congestion causing schemes the greens have rolled out, which certainly have been having a negative impact.

Which schemes?! Maybe the London Road or A259 East bus lanes? Oh I forgot - these were installed by previous Tory and/or Labour administrations that won't change anything the Greens have done if they gain power next May!

Funny how motorists love moaning about cyclists on Hove prom not being prosecuted etc, but defend their 'right' to speed in 20mph areas!

The sad thing is that "motorists" get all upset about lower speed limits, and yet they benefit from them as much as everyone else does.

20mph means less taxpayers' money wasted on road traffic collisions, less pollution (yes, look it up, 20mph limits result in lower pollution due to less acceleration), less traffic (more people will choose to walk, or cycle, instead of using their car for every trip), and smoother traffic flow (it's easier to pull out of a side road into a 20mph stream of traffic than into a 30mph stream). Our towns and cities become pleasant places to live and work and visit, and much less dominated by motor traffic that is noisy and smelly.

Motor vehicles are extremely useful, but hopelessly inefficient as local urban transport. Remember that next time you're stuck in a traffic jam while pedestrians and cyclists keep moving past you!

The other odd thing about the "anti-20mph brigade" is that they are so blinkered. You only have to look at other towns and cities to see that 20mph (or 30km/h) is considered to be the sensible speed limit for motor vehicles in places all over the world. What's more, in surveys around 70% of the population are found to be in favour of 20mph limits, and this approval rate goes up after 20mph limits are installed.
