In the context of elasticity of demand and taxation, if the relationship between price increase and quantity demanded is similar to the relationship between a steep hill and a bicycle's speed, what would represent a flat road?

In the context of elasticity of demand, a steep hill represents a situation where a small increase in price leads to a large decrease in the quantity demanded. This means that consumers are very sensitive to price changes, just like a bike going uphill slows down significantly. On the other hand, a flat road symbolizes a situation where the price increase does not significantly affect the quantity demanded. In this case, consumers are less sensitive to price changes, meaning they will still buy similar amounts even if prices go up. For example, if the price of a necessary medicine increases, people may continue to buy it regardless of the cost, showing inelastic demand, much like riding smoothly on a flat road.
