These are the tunnels of leaf miner an insect grub that lives between the skin layers of the leaf and eats it's way around until it emerges as an adult.
Its an aesthetic reason. Most tracks are red because older tracks (before man-made surfaces) were red cinders.

It looks like the inside of a car door. There's linkages and window tracks and stuff.
Caterpillar tracks consist of heavy steel wheels and treads that are comprised of heavy steel plates. These materials are far more resilient to grenade shrapnel and machine gun fire than wheel rims and rubber tires. Even if you were to fill the tires with that heavy foam they use in forklifts the tracks are still more durable than tires. ~ The large surface area of the coninuous track spreads the considerable weight of the tank more efficiently rubber tyres. This enabes "continuous tracked" vehicle to move across soft ground with less likelihood of becoming stuck due to sinking. The prominent treads of the metal plates are both hard-wearing and damage resistant, comparisoned to rubber tyres. The treads of the tracks provide good traction in soft surfaces but can damage paved/tarmacadum surfaces, so some tracks can have rubber pads installed for use on these surfaces.
well the dog gets in the dirt and than when it comes in it tracks the dirt inside
It's posible, if someone tracks dirt in, or you have potted plants with yard soil, but not very likely.
it all depends, everyone has there favorite.
