Which of you did this?
They’re unhinged.

“The alliance of British drivers worked to get Livingstons congestion charge rolled back”
What ?
Unless the cyclists dinner has been buried deep in the earth for hundreds of millions of years it doesn’t matter.
Wasn't that calculation made on the basis of the cyclist eating nothing but free range beef etc.?Surely a cyclist is using more calories and consequently eating more than a driver, and that food requires fossil fuels to produce and transport.
The only time I've ever voted for a Tory was for Boris, to kick wife-beater Livingstone out so he couldn't expand the congestion charging zone.
It worked

it wasn’t extended westwards but seem to remember that having more to do with Madonna through her to toys out of the pram than the ABD.It wasn’t rolled back though was it ?
No difference! Those sweaty people on bicycles emit as much CO2 into the air as a car."
Average speed of 8mph for the bike? Lol, no.This is the original claim:
"The supposed dangers of manmade global warming from excess carbon dioxide (CO2) generation is often used as an argument for junking new road construction projects and otherwise discouraging car use. But in Europe someone has actually done the calculations!
Bicycles: 4 adults cycle 5 miles to work at an average speed of 8mph, time taken 38 mins (0.63hr).Exercise breathing rate: 6 cub metres/hour, so cyclists exhale 4 x 6 x 0.63 = 15.1 cub metres air.
Exhaled air contains 4% carbon dioxide (CO2), 1 cubic metre exhaled air contains 73.3g CO2. So the amount of CO2 exhaled by the four cyclists is 15.1 x 73.3 = 1108 g.
Car: Four adults travel by car, travelling 5 miles at average 22mph, time taken14 mins (0.23hour). At-rest adult breathing rate is 0.4 cub
metres/ hour. So four adults in car exhale 4 x 0.4 x 0.23 cubic metres air = 0.37 cub metres air. 0.37 cubic metres exhaled air, 4% CO2, contains 0.37 x 73.3 = 27g CO2. The car exhaust emits 215g CO2 per mile (modern, high mpg), so CO2 emitted is 5 x 215 =1075g. Total CO2 emitted by car and 4 seated adults is 1075 + 27 = 1102g. (from Bernard Abrams)
No difference! Those sweaty people on bicycles emit as much CO2 into the air as a car."
Indeed. That average speed would suggest that cyclists actually stop for traffic lights and respect regulations governing one-way streets or cycling on pavements in their journeys.Average speed of 8mph for the bike? Lol, no.
More motorists than cyclists jump red lights.Indeed. That average speed would suggest that cyclists actually stop for traffic lights and respect regulations governing one-way streets or cycling on pavements in their journeys.

i don't think i've seen any motorists jump a red light (bar emergency services, of course) for quite some time, but among cyclists it is common.More motorists than cyclists jump red lights.
I see it daily because I look at the traffic light not the pedestrian crossing but Google it if you don't believe me.i don't think i've seen any motorists jump a red light (bar emergency services, of course) for quite some time, but among cyclists it is common.
Again, lol. I ride on the roads, and stop at all lights. The simple truth is that is city traffic I’m just way, way faster than any car.Indeed. That average speed would suggest that cyclists actually stop for traffic lights and respect regulations governing one-way streets or cycling on pavements in their journeys.
so how many cars a day do you see jumping red lights? 1? 5? 10? 50? i'm talking about traffic lights, not about pedestrian crossings for the obvious reason that that's what people jumping red lights jumpI see it daily because I look at the traffic light not the pedestrian crossing but Google it if you don't believe me.
Eh? Do you even know what a pedestrian crossing is?so how many cars a day do you see jumping red lights? 1? 5? 10? 50? i'm talking about traffic lights, not about pedestrian crossings for the obvious reason that that's what people jumping red lights jump
yes. just to make it plain to you i'm talking about cars going through lights that for them are red, not them going through lights that for pedestrians are red, whether these lights are at a pedestrian crossing or a junctionEh? Do you even know what a pedestrian crossing is?
No shit. So am I. You don't seem to know what a pedestrian crossing is and you haven't come back with any statistics to say I'm wrong so not sure I can be arsed with this.yes. just to make it plain to you i'm talking about cars going through lights that for them are red, not them going through lights that for pedestrians are red, whether these lights are at a pedestrian crossing or a junction

And yet people have clearly asserted the opposite all over the thread, in fact you are right now, and never been asked for proof.Err, it was you that made this frankly bonkers claim -
- it's for you to come up with stats to prove your claim, not for others to disprove it, that's how things tend to work around here.
There are as you ought to know six sorts of pedestrian crossings although here I'm only referring to the ones with traffic lights. You haven't come out with any stats so I don't think you're really in a position to be arsy about thisNo shit. So am I. You don't seem to know what a pedestrian crossing is and you haven't come back with any statistics to say I'm wrong so not sure I can be arsed with this.
