Stopped by police cycling with child in childseat

I've never understood those top tube mounted child seats, they wear through frames, have the weight of the child at a really awkward balance point and don't offer the same kind of support that a rear mounted childseat has.

Makes a good wind-break ...
Seriously, weight in the center of the bike, as opposed to right over the back weel, the kid can see things, you can talk to them ...

Edit: oh and WAC etc. for the copper
