Most country's have a freeway or highway system that contains a lot of cross roads. Most freeways allow people to drive long distances where every driver on the freeway is driving their car fast. A lot of freeways intersect and allow a driver to make a round trip. If you use a GPS, then you can set multiple destinations to calculate a round trip. For example, drive the 92 south, the 45 west, the 31 north, the 78 east, and back to the 92 south. This is an example of a round trip or freeway lap. If you GPS your local freeways, then you will find similar intersecting freeway roads to the example above. Car companies created the freeway system, and the freeway's geography forces car companies to build a specific car. Most sport cars, muscle cars, performance cars, grand tour cars have a fuel tank so that the driver can survive their round trip on one tank of gas. Calculate a local freeway round trip similar to the example above, and you will find the distance of your round trip is equal to or less than one tank of gas and the car's MPG. For example, most performance cars are 10 or 15 miles per gallon ( MPG ) and their fuel tanks are small, about 10 or 19 gallons. If your performance car gets 10 miles to the gallon and has a gas tank of 15 gallons, then your performance car can drive 150 miles before refueling.
Most freeways have good roads and a good view. Freeways allow drivers to drive on the edge of the ocean, in the middle of forest trees, or on the side of a high altitude mountain. Long stretches of freeway usually have a speed station that calculates if you are driving illegally. Driving the speed limit is fast. It is rare for a driver to drive the number on the speed limit sign for long periods of time. Other drivers change lanes. Drivers with passengers attempt to cross multiple lanes to drive the "carpool lane". Trucks attempt to stay near the on ramps and off ramps. Most freeways are stop and go. New GPS systems have a traffic feature. Drive the freeway when there is little to no traffic in order to perform a freeway lap. Some GPS advertise themselves as radar detectors, yet drivers have to use their phone while driving to report these radar detectors and speed stations. Using your phone while driving is illegal. Calculate a round trip similar to the two examples above. Test if you are able to complete one round trip on one tank of gas. Perform freeway laps on different days to record your personal time. Drivers will find most freeway and highway roads allow for a round trip on one tank of gas or less. Do not let the view distract you, watch for other drivers, drive the speed limit, "a ford and dodge" the radar speed stations, and survive your calculated freeway lap.
