when air is pushed forward, is has less pressure to the sides then in front, causing a vacuum on either side. when the truck speeds by, it causes this affect on a descent sized scale, large enough to pull your car.
because your going forward at a faster speed its hard to explain
They crash because of less pressure
When two layers of a liquid in contact with each other move at different speeds, there will be a force between them. See Wikipedia for details.
There are many factors that can cause a vehicle to drift when moving at highway speed. First off is the alignment of the vehicles tires. At slow speeds this may not be noticable to the driver, but as the vehicles speed increases, the small inperfection in the tires alignment becomes magnified, causing the vehicle to pull (drift) to one side or the other. This can also be caused by the slight variations in each individual tire's pressure as well. Second, the drift can be caused by force of and direction of the prevailing wind passing over the highway. In addition, as the vehicle increases in speed, minor inperfections in the vehicles aerodynamic shape (tailpipes, muffler, dings, dents ect) can alter the force of the wind passing both above and below the vehicle causing drift. Weight distribution in the vehicle also plays a part in this. More weight on one side will cause the vehicle to pull in that direction. This is just a few of the basic reasons.
The effect of a roof rack on gas economy is negligible -- until you place a luggage carrier on the rack. The increased profile of the carrier increases the car's air resistance, which becomes significant at highway speeds.

At highway speeds, YES!

NO! Mopeds generally are 50cc or less. Some states allow highway travel with a minimum of 150cc which is suicidal, unless it can maintain 70mph. Personally I would go no less than 250cc for highway riding, and more like 400cc for long distance touring with or without a passenger and with the ability to pass comfortably at highway speeds.

If by this you mean only "hot heat" when drive at highway speeds likely thermostat bad and/or almost stuck and takes long time warm up from high engine RPM during highway driving.

A US highway is an all access highway, like a main road; it includes businesses, houses, and direct intersections. Top speeds on the average US highway are 55 mph. An interstate highway is a limited access highway that is meant for commute. It includes no property entrances, and interchanges at high speed. Speeds range from 65 to 75 mph (about 90 to 105 km/h).
Warrego Highway is open as of 14/1/11 from Toowoomba to Dinmore with reduced speeds on many sections.
I don't use mine until I reach highway speeds.
Because at higher speeds, the wheels begin acting as gyroscopes, helping to keep the bike steady.
running out of gas??
