How can I open the gas tank on a 2020 Honda Odyssey?

Can I turn off the speed-dependent volume control feature in my BMW? It’s super annoying and doesn’t really seem to help much with playing over the road noise, so I would love to just turn the feature off.

I’ve been having traction issues in my pickup lately, so I’m trying to find a good way to weigh the bed down. I know you can purchase weights specifically for that purpose, but I don’t have a lot of money to spend—what’s the cheapest way I can weigh down my truck bed?

My teenage daughter plays hockey and all of her gear reeks of sweat (and she does, too, if I'm being honest). Now the leather seats in my car are starting to smell funky because of how much she sweats! I obviously can't stop her from sweating, and I'd never stop her from playing hockey, but how do I get rid of the smell?
