So that's what you'd really like to see?
Cycling alone wouldn't do that,reliable,affordable,clean and effecient public transport would tick the boxes for most people on short to medium range travel with cycling an alternative for short hop travel,but the answer is investment in infrastructure,something successive governments have failed miserably on preferring to spend,spend,spend,on roads and motoring,leaving commuter and leisure travellers alike with little choice but to use the car.
The spin offs from that shortsighted approach is increasing pollution made worse by slow or standing traffic in towns and cities on overburdened roads and huge outlay of taxes on such a dead end transport strategy,resulting in high numbers of citizens dying or sick as a result.
It could be so much better but won't be until someone by necessity begins to think outside the box,though with motoring bringing in so much tax revenue it'll be an uphill struggle for any forward thinking government and the UK has been short on those for a very long time where a transport strategy,or any other strategy FTM,is concerned..
