1) It is expensive to introduce
Probably not anywhere near as expensive as new roads. But maybe local congestion zones are a better option than a national scheme.
2) Need to drive does not correlate neatly to income
Nor does the need to eat.
The impact of congestion and the associated traffic fumes in built up areas falls on everyone who lives, goes to school, or works in our cities, regardless if they choose to drive or not.
3) I don't believe it will be 'revenue neutral'- it gives politicians the chance to sneak in a tax rise by the back door so to speak.
I don't get the problem with people not wanting to raise tax money. It has to come from somewhere. Better put extra tax on an activity which our dependancy on is making us fat and driving people to to sedatory life styles.
Even with the opportunity to get extra taxes 'they' claimed it will be revenue neutral. So with road pricing the Tax burdon seems to move away from low milage rural motorists to high milage urban drivers. It is urban driving that causes the most damange and to which there are more alternatives.
4) Civil liberties implications
There could be an issue here. But many people in London seem to be happy having their tube journies linked to them when using cards to pay for their travel. Or you pay cash to avoid this association. I'm sure you could arrange payment for road pricing in the same way.
5) The real winners will be big business, and the rich (who will have the benefit of clear roads they can easily afford)
You could easily argue the other way around of course. Many business trips really need to be done using a private vehicle and there is no option. There should always be provision to commute in cities using public transport. It seems that rural roads will cost less and so the rural driver may actually be better off.
I hope that road pricing will lead people to think about travel in our cities differently. As alternatives to driving become relatively cheaper more people will use them. Our roads become less clogged making them easier to use without having a car wrapped around your body. People might just walk and cycle more.
6) For the first time in history ordinary people are able to go where we want when we want- lets not throw that away.
Yes. I could fly from London to Cornwall tomorrow if I wanted, but I do not see that as positive.
Road pricing will not stop 'ordinary people' driving, who ever they are. But with road pricing I can see a mechanism which increases use of the roads by everyone, not just motorists.
