from the M11 into London save?
The increase in ability to move people quickly and safely with Public
Transport, is huge compared with demolishing houses and concreting green
spaces as required for roads. Create better quicker public transport and
many will desert their cars leaving much more space for the Jeremy

We have to be careful about investment in public transport too. It is not on
unshakable environmental grounds. Many people assume that a journey by
public transport reprents a car off the road. But this is hardly ever true,
only about 10% of people would have used their car if the public transport
service was unavailable. I suspect, in the long term, that would actually be
0%. If there were no East Coast Mainline, how many people living in
Peterborough would be driving into London for work? Because they can do it
on the train in 45 minutes, Peterborough is a commuter town, despite being
75 miles out of London. This is not environmentally beneficial.

Public transport does need investment, but it should mainly come from fares,
rather than public money.

I agree that we shouldn't do things to encourage more and longer trips,
but isn't that just what we've done for private cars? FREE roads paid
out of general taxation, and cheap petrol obtained by beating up poor
and vulnerable countries?

Since doing some stats on trips on Great Western Main line into London
from Reading in early 1970's I've felt we've made commuting fares too
cheap. Then an 'annual' season ticket gave a daily rate(assuming 220
tpa) cheaper than a cheap day return. Perhaps what we need to do is
ensure car trips pay true cost?
