Actually modern Jet Aircraft do. But not as much as race cars. That's because of things like where you have to look and ejection seats.The F-16 seat is the earliest reclined seat I remember off the top of my head. It's not obvious but it's reclined 30 degrees back as a feature. Rotating seats really isn’t worth the added weight and cost.Extensive testing has been done in the prone position - on back or stomach. Visibility for air to air work is inadequate. Not to mention it’s actually less comfortable for the pilot. Note above chin rest. And dangerous for ejection seats.Quora : Was the F16's reclined seat design copied by other fighter jets?

No, not required . You have to learn Only that one which are in news in last one year.Actually it's UPSC, questions are not asked only about location of national parks but also other related things of national park like extension, species, Rivers , hills , states, North South order etc.. for example this year (2020 Prelims) Desert National Park and see 2016 Prelims questions in images, if you learns all related things for all National parks then no cost benefit and also not required as you need to be quite SMART in upsc preparation.

Because it allows them to take long road trips or do regional business trips in their cars conveniently and cheaply, often with no transaction costs.The cost savings when driving a Tesla long distances are absurd. People visit all 48 contiguous US states on road trips and pay under $100 for fuel. People drive to Florida with no cost for fuel. People drive a few hundred miles for business with no fuel cost.And since Teslas have much lower vibration, and many will do the driving for you on major roads, people can drive safely and comfortably a lot further. Hell, the current Tesla autonomous features will drive the car from one Supercharger to the next with only minimal driver intervention in the last 100 feet or so.You can’t sleep or work outside of hands free phone calls while the car is driving, but you arrive a lot less stressed and tired than if you did the driving yourself. Safer too, as Teslas have collisions a lot less of the time when the car is in control.
