Thanks for the physics lesson. In order to have kinetic energy, SOMETHING had to GIVE IT that energy. In your car, it is the gas that gets the car going. It coasts due to kinetic energy. but it won't coast for a year. Kinetic energy is lost in many ways, and THAT cannot be recovered. The friction of the air alone will eventually stop it.
So, instead of attempting to teach an engineer about physics, why not question what the energy source is for this so-called car? Inquiring minds want to know THAT. I fricking guarantee what what has been said is impossible, and they have not told us yet what will power this car.

Nonsensical. Vehicle kinetic energy is lost due to tire friction , wheel bearing friction , gravity (going uphill) and air resistance. Speed slows due to those factors.

"...Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes...."
