As travel in the US picks back up thanks to COVID vaccine rollouts, people continue to prioritize safety and social distancing. Travelers are turning to road trips and renting cars in droves, which has created a national car rental shortage and seen prices in the most popular locations skyrocket. In some places, rental prices have surged to as high as $700 per day, so you may need to rethink your road trip if you were hoping it would be a wallet-friendly vacation.
