Even if your vehicle has air conditioning, past a certain point (say, when your aging mid-level sedan has been driven for 6+ hours on local streets in direct sun the whole time), a lot of them won't be able to keep the cabin cool enough to prevent discomfort. Sweaty buttcrack almost ended my run with Lyft & Uber prematurely. My passengers were fine with the a/c on max, but I was getting more sun & moving around more. What saved my ass was a fan-infused car seat cushion powered off a standard car outlet. It's most effective once you've already started sweating, but it changed the game for me. I now consider it essential equipment.
