Even with the ability to connect the world through the internet, transportation is still a major component of the modern world. Goods ordered online or bought in stores must be shipped to reach their end users. The components for many modern goods come from all over the world, and transportation is part of their acquisition. Services for homes and businesses are another facet of the world where people must use transportation to provide them. All of this adds up to more vehicles on the roads than ever before.
Whether a vehicle is a car, large truck, boat or airplane, it needs to function correctly to get where it is going. Building and selling vehicles is only the beginning of their journey, and keeping them on the road is the work of mechanics. These craftsmen are now highly trained individuals who use computers to diagnose many issues, but servicing vehicles always comes down to taking them apart and fitting them back together by hand.
When a vehicle breaks down, a tow truck is often dispatched to fix it or haul it to a shop. Many drivers who work for towing services have their own mechanical abilities, and they can often fix small issues with simple tools. This keeps people and good moving, and it can also save hours spent in the repair shop or at least save a large towing bill if the car can be driven there.
Mechanics for vehicles continue to find their skills in demand, and there appears to be no end to it. They are needed for routine maintenance as well as emergency corrections when people get stuck. Their tools may now routinely call for electronics and computers, but their innate ability to diagnose and correct engine issues is the craft they still practice every day.
