You can't be a pilot unless you have a certain qualification and go through a bunch of exams. You can't be a train / loco pilot unless you again go through a set of exams. However come driving vehicles on road, there seems to be no qualification - especially in India. There may be other countries in the world where the situation is similar to here in India. Please excuse my ignorance here.
Now coming back to aircraft pilots case. It is understandable why they should have the necessary certification. You need to handle tons of instruments and it's enough you can read the numbers of those devices. You also need to understand what they mean. And in some cases even use what those instruments are telling you and take life saving actions.
What about loco pilots or those who operate ships? I guess the complexity may be less compared to pilots but they do have manage a vehicle that is pretty big.
Now coming to drivers on road, they seem no qualification. Kids start driving 2 wheelers on road. The technical qualification exam or driving test is a sham. I agree that the vehicle size may not be big, there are no hoards of instruments to handle. However what the sheer number of vehicles? What about the fact that pedestrians and bicycles share the road with these vehicles. What about the different size of vehicles on the road? Educational qualification may not be required. However I'm sure some common sense training may be a good. Also the time has come to makes those "driving tests" to make it more stringent.
