Re: Every breath we take: the lifelong impact of air pollution

Anyone still believe the industry propaganda that the latest diesels with AdBlue injection are "clean"? You should watch this: http://www.channel4.com/programmes/dispatches/on-demand/67343-001 It's an expose on the widespread disabling of HGV emission controls in the UK. Pretty shocking al...

Re: M1 crash - can someone explain

Evidence shows that having a 'hands free' phone conversation whilst driving impairs reaction times even more than being over the drink drive limit. http://news.bbc.co.uk/1/hi/uk/1885775.stm This has been known for over a decade.....which begs the question: does the employment contract for a Fed-Ex H...

Re: cars buck falling CO2 trend

http://www.bbc.co.uk/news/science-environment-43308567 But Paul Morozzo, from Greenpeace, told BBC News: "SUV sales have had more of an impact on average CO₂ emissions than the shift away from diesel. think this is one of the most telling comments in the whole article +1 Tackling the scourge o...

Re: Diesel - seriously thinking of giving up cycling

Yes this illustrates the point I have been making. Streets which have already had private vehicles banned completely still have pollution levels way above what is acceptable. The street in Glasgow pictured above is a prime example of this. The reason of course is that all those taxis and buses are s...

Re: Diesel - seriously thinking of giving up cycling

A ban on all motorised transport would nail all problems though. :wink: No it wouldn't. If we are going to be pedantic, then bicycle tyres, shoe leather and horses hooves would also cause create some particulate matter, perhaps we could cite this as a reason for inaction? In the real world, changin...

Re: Diesel - seriously thinking of giving up cycling

There is another important day in court tomorrow in Germany. The German federal courts will have the final say on whether cities (including Stuttgart - home of the mighty Mercedes Benz) are allowed to ban certain types of vehicles as a response to chronically bad air pollution problems. https://www...

Re: Diesel - seriously thinking of giving up cycling

A total ban on busses and taxis using diesel would nail that particular problem overnight.

Re: Distance on battery

It might seem like a lot of faff but charging everynight after 19 miles will make your battery last a lot longer than if you were wait until the bike had covered 38miles. Known as 'depth of discharge' - this has a big effect on the useful lifespan of lithium batteries. https://energymag.net/dod-dept...

Re: Diesel - seriously thinking of giving up cycling

Perhaps now ...

Re: Diesel - seriously thinking of giving up cycling

The argument is about the malevolent form of nimbyism involved in agitating for a switch from diesel to petrol cars. We can do the switch and improve our local air quality at the expense of dumping the problem of increased carbon emissions on everybody else. Does anyone have a moral justification f...

Re: Diesel - seriously thinking of giving up cycling

The pollution in vehicle exhausts isn't a trivial matter. How they smell is. If anyone argued that we should ban all petrol engines 'cos we don't like the smell of Hydrogen Sulphide we'd all laugh at them. Except it is extremely rare these days to smell H2S from a catalyst. The smell of diesel exha...

Re: Diesel - seriously thinking of giving up cycling

I think we have our wires crossed!

I am criticising MartinC's post because it is apparently trivialising MickF's concerns about not being able to escape diesel exhaust whilst out riding.
