Sorry yes my maths was wrong on that.
But again this scheme's focus is making cycling attractive, so the primarily spending should be on that. How much funding has been effectively given over to car drivers? I say effectively, as despite being allowed to cycle on these roads, most don't feel that is an option. I can cycle on 70mph Dual Carriageways if I wanted to, but I wouldn't dream of doing that.
I cycle on the A105 and the A1010. Since my commute is around 13-15 miles to university, using minor roads is not an option as it would take an eternity. If you think that it is possible to cycle on quiet roads, show me the route. Not only do they take longer, but they do not feel safe against muggers, for example.
If I wanted to take 'minor' roads next to Green lanes I could use Old Park Ave, Old Park Ridings. This was even more stressful than the A105 because there were more parked cars, and higher inclination, so I had to constantly go into primary while being quite slow. The road had loads of drivers on it.
The other way is through Halstead Road, and that still requires you to cycle up to Church Street ( when southbound ) and then again take multiple detours. Finally you must go through an underpass when reaching the A406, something that doesn't feel safe at night.
Yes in the Netherlands it is seen as safe; but it isn't just safe, it is also convenient: the cycle paths are on main roads as well, forming a high density grid. Cycling is also usually faster for short journeys by virtue of the design. You claim that cycle paths can't be put in place but they do exist on roads of similar width to the A105 in the Netherlands. Just look at the distance of the building to building ( or front garden to front garden) width along the A10. You just cannot call it narrow.
Your idea that we should keep cyclists away from main roads and along back streets just won't encourage cycling. The River Lea, for example, does not have many entrance/exit points and it is at the edge of Enfield. I myself personally use it to cycle to University when I can as it is just as fast as the alternatives, but for most people that won't be true.
We've tried education and it doesn't work. For example, Michael Mason was hit from behind last year. He was an experienced cyclist, having done so for many decades. It didn't stop him from being killed. Education also won't stop being from being frightened so as not to cycle at all.
By the way there is no evidence that Hi Vis jackets work and it is simply victim blaming as far as I'm concerned. Hi Vis jackets and helmets also discourage cycling.
Please don't tell me you've used the cyclists don't pay 'road tax' argument. You do know the roads are funded by council tax, that VED or other motoring taxes are not hypothecated to road building, and that most people that cycle are also drivers. Drivers are in fact subsidised by at least £10 billion a year according to this study (http://webarchive.nationalarchives.gov.uk/+/http:/www.cabinetoffice.gov.uk/media/307739/wider-costs-transport.pdf) and providing funding for good quality cycle infrastructure yields return 5.5 times higher than the costs according to the DfT (https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/348943/vfm-assessment-of-cycling-grants.pdf).
The point of the pavements argument is to illustrate what would happen without infrastructure for pedestrians.
Now for your upsides of cars:
It is true you are protected from elements. I don't see this as a massive problem though:
By continuing to drive you are also worsening climate change and thus making the weather more extreme, but I would hold the Government to account on this.
The reason driving is faster is because the environment favours cars. As I said, in the Netherlands cycling is faster because it has the advantage.
However, since average traffic speed in central London is 10mph or something, cycling in many cases is faster, and this is one of the reasons some people cycle. For me being slower on most days is worth it just for the times I filter past miles of vehicles.
While I agree it is bad drivers that kill people, it doesn't detract from the fact that motor vehicles make this a possibility. Cyclists rarely do anything of the sort and so they pose a far smaller risk on others. If more people cycled, the risk would go down, even if they weren't more competent.
I fail to see how driving to the gym specifically is an advantage. How about cycling to the gym, or buying your own equipment? How about cycling when you can so you get exercise without having to put aside time for the day? Good for people with busy schedules.
I agree that bicycle aren't really suited for long distance journeys, and that is one of the advantages of cars, as I've said before. Most journeys aren't long distance: it is with these journeys we should be cycling more.
You can have a bicycle for each member of the family.
Most parents aren't free 24/7. And even if they were, do you think that having to be driven everywhere and be dependent on your parents is better than being able to cycle there yourself? Tell me how it's positive that children are exercising less and cannot play freely on the street.
Why are you bringing in railways into this? My point is that road building is a futile endeavour because cars will always fill in the gap. Bicycle damage the roads much less than cars do.
The last reason just sounds like you are clutching at straws. So is this an advantage of every conversation topic? Even if it were an advantage, you will notice that it doesn't depend on usage of a car. So, we could still have a sensible society which uses bicycles for shorter trips, and talk about cars anyway. People still drive in the Netherlands and car ownership is higher there.

Cycling now receives consistent funding from the government and is integrated into the transport policy.
Cycling to school in the Netherlands is very common, so perhaps your son wouldn't be so embarrassed if it were normal.
Edit: I must again point to the fact that cycling is beneficial to everyone.

The scheme will have to take some road space for cycling, though, as there is no real alternative if we want cycling to be attractive.
You seem to have a defeatist attitude. Instead of saying that all of this is not possible, as some people said in the Netherlands, let's actually try rather than sticking to the horrible status quo.
