What vehicles harder to operate than a car?

Some industrial trucks are more difficult to use than normal cars. They have a manual transmission that can lead up to an 18-speed, which can be difficult to shift. Older trucks may have only the normal 4 speeds, but prior to the 1950s they lacked something called syncros which are found only in manual transmissions. These syncros allow the driver to make an easier change from one gear to another. Without them the driver had to match the engine speed and vehicle speed, while often "double clutching" and grinding gears just to get the truck into the next gear. Personally I have had to do that with a dump truck that has a 20-foot bed, and getting me to drive that thing was like pulling teeth. But there is a point where you are trying to get it in gear so long that you have lost so much speed you have to down shift instead of the original up shift you were doing!
