(Note, I'm in a cab, not driving whilst typing!!)
We're travelling along one of the busiest roads in London and the traffic is actually moving for once (love Fridays when lots of schools are off) - and the vehicle in front is a motorbike with a child riding pillion. The child is small but big enough to reach the footpeg (although s/he seems more interested in sticking his/her feet out at the moment).
It has really surprised me - ok so I'm not a biker and fully prepared to be told I am overreacting, but would (i) you take a child on a motorbike and (ii) through Central London where so many bikers, motor and pedal, get into tangles with lorries and buses?
