Friction is present on Earth anywhere there is movement, and it can affect objects in all sorts of ways. It generates heat, which is why hands warm up when people rub them together. It can also slow down objects—car brakes use friction to reduce speed—and it causes general wear and tear, which is why drivers have to replace their brake pads—and tires—every so often.
that's why scientist trying to produce frictionless wheels ....

Answer:
Friction is the force the opposes motion. So, even if we somehow produced a very high speed vehicle it would have a speed limit due to friction. That is why scientists are trying to produce frictionless wheels because with frictionless wheels we could achieve like a very very very very very high speed on vehicles.
