I think increases in sales of scooters and bicycles and other modes of lower priced (to operate) vehicles, as well as their sales prices, is mostly due to gas price increases. That's a familiar song.
And where in the USA is this 8% inflation increase? I know that inflation for gas during the month of March and April (each) at WAY over 8%. But the overall average for the previous 12 months is still under 2.5%, and the overall average for just April 2021 is 4.2%. With 10 out of the previous 12 months being below 2% starting last May at .1%. It's just certain individual industries, like fuel and travel related items, that have skyrocketed compared to the previous 12 months. Still not the highest rates seen in the last 20 years for many items. Inflation is up overall due to the economy trying to restart after the Pandemic. But a blanket 8% figure needs a bit of definition.
