air con puddles, - how bigs yours?

err, as per my other post re steam injection it appears the puddle under my car is clear water and so its thought that its air con water. thing is its a chuffing big puddle on mine and I'm really struggling to think it can all be that.

now I tend to drive a min of 40 miles ( home to work is 54, home to caravan is ~ 45 ) etc and I have mine sat at 18.5 on both zones.

so do teh rest of you also get a puddle? mines sort of about teh level in line with the radiator near the front offside wheel. I know there is a tray so stuff tracks about..
