Sure. There are bike and scooter booms whenever the price of gas spikes.
Added on edit, from a 2011 LA Times story I just Googled:
Renewed interest in scooters this year is largely attributable to gas prices, which in California leapt above $4 a gallon before dropping in recent weeks. In 2008, when gas prices last spiked, scooter sales escalated to the highest level ever in the U.S. with 228,000 sold.
Sales plummeted in 2009 and again in 2010, when only 77,000 scooters were sold.
Can you imagine trying to plan for next year in a business like that?
