840 watts seems high.
As a point of reference, the input power connector on Tesla's new HW4 computer is rated for 10A @ 16v, or 160 watts.
In fairness to the authors, HW4 was not yet released when this paper was published.

It still isn’t a lot compared to moving the car but it is quite a bit of power. For a car with 100kw/h battery pack and a range of 500km a 1kw driving computer would reduce the range by about 5% which is about as much as having the air conditioner on.
