Final answer:
Identifying cars that surpass the fuel efficiency of an airplane with 90 mpg per passenger is challenging as most cars do not reach that level of efficiency. The most efficient hybrid cars may approach 50-60 mpg, but still fall short of the 90 mpg benchmark.
Step-by-step explanation:
The question pertains to a comparison between the fuel efficiency of an airplane versus a car. In this scenario, we're given that an airplane gets 90 miles per gallon (mpg) per passenger. To determine if there's a driving option that uses less fuel per person than a fully-occupied airplane with that fuel efficiency, we need to find cars that match or exceed this fuel efficiency.
As of now, finding cars with fuel efficiency of 90 mpg per person is very challenging because most conventional vehicles do not reach this level of fuel economy. Even the most fuel-efficient hybrid cars available on the market typically reach up to 50-60 mpg under optimal conditions. Therefore, it is not easy to find cars whose performance is at least as good as a fully-occupied airplane boasting 90 mpg per passenger.
It is important to consider that car fuel efficiency can be somewhat improved when carrying more passengers, effectively increasing the mpg per person. However, achieving the 90 mpg per person mark would require a car to carry several passengers without significantly compromising its fuel efficiency which is generally not practical in everyday scenarios.
