Suppose that we were to install bicycle pedals into a passenger car, say a civic coupe, in such a way that pedaling is as mechanically efficient as riding an ordinary bike. Further suppose that we have a transmission with whatever the appropriate gearing would be for actually moving the beast under pedal-power.

What would be the maximum speed of such a vehicle for an ordinary operator who puts out about 200W?

The following variables reduce the ambiguity of the problem... Please comment if more info is necessary:

  • Human power output 200W
  • Sea level
  • 2019 Honda Civic Coupe
  • Power lost to friction on gears and whatnot: 0%
  • Power lost to road friction and air resistance: 100% at peak velocity

UPDATE: To be clear, I am not asking an open-ended "what if" type question. Specifically, I am not open to arbitrary answers about possible things resulting from a pedal-powered car. I am specifically interested in its speed limitations, which is a well-grounded physics problem. This is a "practical, answerable question" in the sense that the force input via human pedal-power and the force applied to the car via friction and air resistance are measurable and reasonably well-known quantities. Therefore, the maximum speed for a given car propelled by an average human operator should have a well-defined and unambiguous value. In other words, there is one and only one numerical answer to this question, and it is therefore not open-ended.
