Ask the right question

I wish to give this example about asking the right question.

Suppose the question is - how do we make our buses run more smoothly without the jerkiness. Can we use technology to reduce the jerk?

This may be the wrong question.

The right question should be - should we replace buses by trams that run on rails, like in some cities?

Buses have to run on fixed routes. When running a fixed route, it is better to use rails as there is no need to need to move from one lane to another. The tram only need to stop and it can be done in a smooth manner.
