I congratulate you on being a good parent, you certainly do provide for your kids in spades and i admire that. I also took your location as being Cheadle Hulme which does have very good transport links.
I agree on the 4x4 front, a woman at the top of our street drives her two kids to school in a 4x4, her back garden backs on to the school fields, its a 5 minute walk to the front gate of the school.
I did also say much earlier in the thread that i would invest enormously in public transport infrastructure and make all public transport free at the point of use for everyone and that work vans would be exempt. The public transport system is piss poor, but that is because of the fragmentation caused by privatisation, where only profitable routes were retained and fuck everyone else.
Something radical has to change, i am pretty sure everyone wants their kids growing up in a clean air environment, you obviously want your kids to be healthy as shown by the activities they do. I suspect most on here want that too.
