You are quite right. Except that you are implying other product will decrease in price while that one increases. Vehicles is a rather large market and an element of supply chain costs, chips are used across so many industries. I would rather expect the majority of product to see an increase in price. We can talk technical terms but my comment was a reflection of the markets at large.
Inflation is the systemic increase in all costs of what a household would buy as money itself become less valuable.
Prices 'inflating' on a single product because there's a shortage of... base materials or whatever is not inflation as an economic term.
