There is plenty of space for passengers and storage. We traded in a Ford Fusion sedan and the Ioniq 5 has much more storage space than that did. One of the long road trips I mentioned was a camping trip. We were able to bring two big tote bins, a big cooler, a canopy tent for the picnic table, folding chairs, sleeping bags, air mattresses, extra blankets, and two dogs on the back seat. As a bonus, we got an adapter that plugs into the charging port and can power a hotplate for boiling water faster than a camp fire (also serves as back up power for my house if the power goes out, can run an extension cord down to the freezer). There is a small frunk, we mostly use that for emergency supplies.
I'm above average height and can fully extend my legs in both front seats and never have issues with head clearance. I like the space between the two front seats as well being mostly open concept as opposed to the closed spaces in Teslas. Feels spacious for every day driving and on road trips can fit a soft sided cooler as well as a food bag.
Seconding Center for American Progress. There are also a ton of issue specific organizations and professional societies that are non partisan, but focus on improving policies that tend to be left leaning. For example Planned Parenthood is technically a nonpartisan nonprofit, but many other health or environment related non-profits have a policy team that tries to advance their cause the best they know how. Being nonpartisan means they aren't limited to speaking with one side or the other and can keep a drum beat going on their issues regardless of the political winds. These orgs could use your donations now more than ever.
