Making Tracks


A bicycle passes along a path and leaves some tracks.

Is it possible to examine the curve of the individual tracks (both tyres have identical tread) and from them say which track was made by the front wheel and which by the back wheel?

Is it possible to say in which direction along the path the bicycle was travelling ?

The image above is just a picture to suggest the context, but if you'd like some accurate curves (tracks) to play with see the Hint
