From Eric Kvaalen, Les Essarts-le-Roi, France
Merlin Reader advises free public transport as one way to have fewer cars on the roads. I advocated that for years, but then learned that it has been implemented in some French towns, and the result wasn’t less car use. The people who used the free transport were those who would normally walk or go by bike (which means they got less exercise!). I think we need more of a carbon tax (Letters, 30 December 2023).
