It can be inferred from the passage that ----.

It is safe to bet that a flying motorcycle will never be a
practical transportation option. Yet, this process has not
stopped an engineering firm in California from playing
the long odds. The company is building a prototype
called the Switchblade, and it hopes to sell a
do-it-yourself kit as early as 2015. Attractive design and
the promise of having air and ground transport in one
package have kept alive dreams of a flying vehicle. A
three-wheel design was chosen because it meets the
definition of a motorcycle, which is not as highly
regulated as cars are. For example, motorcycles do not
need bumpers, which would make a flying vehicle
heavier and more expensive. As the company envisions
it, occupants would sit in the aerodynamic Switchblade,
in climate-controlled luxury with an instrument display
that switches from air to ground readings on landing.
The Switchblade will succeed, the company believes,
because it will transform easily between transportation
in the air and on the ground. If pilots encountered bad
weather while flying, they could put down at an airstrip,
fold in the wings and finish the trip by travelling on the
ground with no manual disassembly. The reality,
however, is more complicated, given that aircraft are
prohibited from operating on roads and tightly regulated
as to how close they can fly to homes, military
installations and environmentally sensitive areas.
