How high would gas prices have to go before you thought about buying a scooter or a moped? You can find a low-end scooter for $800, and even one that goes up to 55mph for under a grand. But the typical median price looks to be closer to $1500. The fuel mileage for scooters is given as being from 50 to 80 miles per gallon. While mopeds are rated at 100+ mpg.
I put together a little chart that can help estimate how much money a person could save by switching to an 80mpg scooter.

After a bit of thought, it seems a natural follow up question is how do you market these to get significant market penetration? Aside from high gas prices, how do you convince someone to switch from car to scooter?
Speaking of scooters, I have to bring up Ron White:
We walk by this little place that rents scooters, and I tell my wife “why don’t we rent one of these scooters and we can just buzz around the whole island on a little scooter?”
She goes, “we are not gettin’ on one of those scooters!”
I said, “Let me rephrase that… I’m gonna rent a scooter.”

I made the argument to my Daddy in college that buying me a Vespa was cost effective–I would stop getting parking tickets at Clemson. With gas prices added into the fact that I’m about to switch to a job that is only 1.5 miles from my house, and I won’t have reserved parking for my first year, I might be revisiting the scooter idea.
