String/Thread

String or Thread connects the flail to the car, it drops the flail when the user clicks, and signals the flail to come back with a long click from the mouse of the user.

When the player has a big flail and crosses the +, he/she may get their flail stuck and their string/thread extends which is annoying because the car moves in a unusual way that the player's car gets electrocuted by someone's flail; and their flail may lose some energy and drops food until the flail completely dies hence the player's car dies.
