You could be right there mate.
What not only this, but most, goverments, either don't realise, or do, and use it as an excuse to overtax motorists, is that the country couldn't survive without personal transport.
If you halved public transport the numbers driven into cars would be miniscule, and easily absorbed, probably without even reversing all the purposely planned congestion creating "calming" provisions that strangle the arteries of the nation through which the life blood of the economy is trying to flow.
However, if you halved car use the public transport system couldn't begin to cope.
Even at present levels, motorists, through their motoring taxes, not public transport passengers, are wasting £Billions on bus lanes that stand empty most of the day, and buses that stand, or, worse, run, empty most of the day.
Even if we could afford to increase public transport fleets to accomodate half of car users, it would be massively inefficient.
But how could we afford it with so many motorists, who actually pay for most of public transport, driven out of their cars?
