I take it you too can’t think of any downsides to reducing the speed limit to 20 from 30? It increases pollution. But then that's part of the plan. You only have to think about it logically, if we stood all day in a road that had streams of traffic doing 20 mph, by the end of the day we'd be coughing our guts up, if those same cars were doing 40 mph, our intake of nitrogen oxides , volatile organic compounds , carbon monoxide , carbon dioxide , particulates, sulphur dioxide and lead, would have been far less. |

Well done Squeezed for at least trying to come up with a justification for not reducing the speed limit in cities like Plymouth from 30M PH to 20MPH. Pollution. OK where is your evidence that such a measure would increase pollution.

Not sure I understand your point Pacifico. The question I posed was “what are the downsides in reducing the standard speed limit in a medium sized city from 30mph to 20mph.” You don’t seem to have answered the question. I haven’t really thought about it before. Until Sunak made it a national issue it felt like a matter for locally elected councillors to decide for their patch. But as it’s now a national political issue I thought I ought to consider it. And frankly I can’t think of much of a downside. I am prepared to listen as I am trying to work out my view but the only reason to keep it at 30 so far is that one driver is apparently unable to control his vehicle which isn’t overly convincing….. Surely the downsides are obvious - increased journey times and more pollution |

Science not your forte is it? Driving faster does not reduce the pollutants. "Driving at lower speeds generally produces less pollution. Many people assume that at lower speeds extra fuel is used and more pollution created, but in fact the reverse is true. Reducing highway speed limits to 60 mph or 55 mph generally reduces emissions. |

Its taken three hours to come up with them Pacifico.
As I said to a previous poster, could you show evidence for the pollution argument.
On journey times, in a medium sized city, I guess the longest journey in a 30 MPH zone would be what 4 miles? How much journey time do you think you would save having a 30mph limit compared to a 20mph limit?

Total bollocks as always. Of course longer journey times will add to pollution. As well as winding up the motorist and road rage incedents will increase. |

Wrong
slower speeds cause congestion, Imperial College London's research into the impact of 20mph speed limits suggests they have no net negative impact on exhaust emissions.

How much journey time do you think you would save having a 30mph limit compared to a 20mph limit? Eh? - if a journey that used to take 10 minutes now takes 15 then that is another 5 minutes when the car is pumping pollution into the air. Surely this is obvious... |

Tell me about this journey through city streets where you can average 30MPH for the entire journey, Pacifico.
Not my experience tbh, I find traffic lights and pedestrian crossings and congestion tend to slow me down. So for a four mile journey I reckon with a 30mph limit it might take me around 15mins, with a 20mph limit maybe around 16mins. Does that sound about right to you.

So add a 20 mph speed limit on that, it will 'slow you down' even more. |
