Can you flat tow a Land Rover Discovery?

The fellas and I are heading up for a week-long trip in the Rocky Mountains. We’re heading up in my RV, but we’re thinking of towing a car along just in case we need to make a quick run into town to grab essentials, like food, water, games, etc. My question is, can you flat tow an automatic car?

I’m kind of a Porsche nerd, and I’m interested in the Porsche Taycan—it’s kind of my dream car, and I’m trying to get up to speed with all of its specs. What is the Porsche Taycan’s turning radius?

How can I make my car door close tighter? I've noticed recently that it feels a bit loose when it's open and doesn't close tightly.
