I would argue there's more to literacy than blindly following instructions. In regards to computers, sure, it isn't difficult to follow some instructions. The worst that could happen? Maybe you mistype a flag and end up recursively deleting a directory. However at least most "damage" done on a computer rarely crosses into the physical realm -- anything lost or damaged can often be repaired or restored inside of a few minutes. So, sure, much of "computer literacy" is simply following instructions that will _usually_ work -- but there's not much hanging in the balance if you mess up. Working on cars though? I would urge strong caution against simply following instructions. Even a fairly "simple" procedure such as jumping your car's dead battery can end in _serious injury or death._ Many people don't realize that their $70 car battery, such an innocuous looking box, can provide in excess of several hundred amps when the current is demanded. Shorting a battery is a quick way to create such a demand. Such a short could result in burns, electrocution, explosions [discharging lead acid batteries give off hydrogen gas], and could even result in a bit of rather annoying spot-welding. Working on certain suspension components can easily create enough force to maim or dismember innocent bystanders.

Working on your exhaust often requires knowledge of your vehicle's fueling and vapor recovery system. Lest you start welding while there are flammable vapors near the rear of the vehicle. "Knowing that you don't know everything" is often a mark of a wise individual. A tutorial may omit some crucial bit of domain knowledge that is commonly taught in the field, but not common knowledge for the average individual. I certainly agree that people should endeavor to broaden their knowledge and skills using the Internet; but Google is certainly not a substitute for an expert's knowledge, experience, and guidance. Without true literacy, in any field, you may quickly end up doing more harm than good.
