Depends on how many people are travelling with per person cost how they can spend on travel. My opinion is car is all budget is fine and you can go anyehere with own car so less petrol cost, but distance matters.
For distance upto 300 kms car or bike is a brilliant options, ofcourse taking in account the road conditions and safety, as you don't want to go on bike and feel like riding a horse.
Train is good option where there is scenic beauty around tracks and it passes through long tunnels.
Flight saves your time and you don't get to enjoy the journey but the destination only.
If you want your journey to be interesting and full of experiences and exploring and you have enough time then bike or car and If you want save time and explore only the place you are visiting then go for flight
Car is a better opt-in if you are gong for a distance travel
but bike is better if you want to get down and experience the roads, people and the landscape around you. wouldn't suggest flight if there is no constraint on time
