I wonder how much the rental companies are using the excuse of the pandemic to artificially raise these prices? They were smart to eliminate overhead (vehicles) when there was no business. But now, knowing that demand is picking up, have been slow to expand their fleets as quickly. These means more profits in the short term, but consumers will eventually be driven to other transportation measures if they cannot get what would normally be more reasonable pricing they are used to.
This is all part of low supply and high demand of capitalism.
