Living in a large metro area with about any service one needs within a few miles(and the big pond to east approx 20 mi away), I don't need to run hundreds of thousand of miles, at 12-14 years old few of my vehicles have much over 100K mi... It's also helped that I've had a company vehicle for most of my working years, those were racking up close to 30K mi per year...
All that said, I currently own a 1996 F-150 beater that has 186K mi, AFAIK in 49 years it has the most miles of any vehicle I've owned... I bought it three years ago with 175K mi, so it's gotten less than 4k per year...
Hobby-ing in used cars I've often seen stuff with 300 & 400K miles, but were not mine...
