We can tax it, and your correspondent points out that fuel duty is a very efficient way of doing that (News, NCE 29 November). We can regulate road use, and that does not have to involve costs to users other than the general taxation costs of managing the system. Or we can put in place incentives not to use the roads.
In respect of the latter, why not make annual season tickets an expense attracting tax relief and reward companies whose employees do not use cars to get to work. Carrots are usually more effective than sticks in
the long run.
