I’m around 195cm. There is plenty of space. I can fit very comfortably into most vehicles (passenger planes excluded). Outside of leg and elbow room, what can you even do with that extra space when stuck in a traffic jam?

You may leave less room for rear seat, adult passengers if you drive a compact car.

It's still manageable, and fine for occasional trips, but I wouldn't choose that car to drive 4 adults daily.

Before the plague forced pervasive WFH, this was every Friday when a bunch of us would pick somewhere for lunch and all pile into the fewest cars needed.

A long time ago I worked in an office like that. I usually biked to commute, so when we had one more person going than cars going to lunch, I just biked to the restaurant as well. Otherwise, I rode in someone's car. Still, none of the drivers did this "daily". Neither this nor sibling comment describe a "daily" situation. If you need a big sedan once a month and big SUV twice a year, just rent at those times and drive something more practical the rest of the year.
