What a lot of rot.
Why not go back to the good old days when car operation was simple and most maintenance you could do yourself such as cleaning or replacing plugs, replacing ignition parts also diagnosing the problem yourself.
If you wanted to check if you had a spark you would ask your girlfriend to hold the plug wire while you cranked the engine by hand  & if she screamed  you had a spark.
If you disconnected the fuel line to the carb. then cranked the engine & there was no fuel flow then you were either out of fuel or had a pump or carb. problem.
If the battery was dead you could hand crank the engine & be on your way or get a push.
Driving used to be a challenge with changing gears, double de- clutching & revving to change gears down  also no power steering or brakes which made it difficult for women along with no make up mirror.
This is progress? We still got from A to B with the older cars.
