Something to bear in mind, how much distance will a rover cover during it's lifetime? Single digit KM? And they also don't weigh much either.

Ah yes, the Curiosity rover was famous for its short travel distances and lifespan.

It's a fair point. Curiosity has "only" travelled about 20 miles over its 12 year life so far. And while it weighs some 900 kilos, Martian gravity is only 38% that of Earth.

Obviously it's absurd to compare the wear and tear on something rumbling around the Martian tundra cut off from any support or maintenance for a decade, but it is a very different use case to your average Earthly car or lorry. What lasts a decade going at 0.1mph for 20 miles in an alien desert is not necessarily going to last a week going at 70mph down an asphalt highway.

Hell, I've walked that in a day, it's really not far at all.

As of December 9, 2020, the rover was 23.32 km (14.49 mi) away from its landing site. As of April 17, 2020, the rover has been driven on fewer than 800 of its 2736 sols (Martian days). As of 30 May, 2023 it had traveled 30.00 km (18.64 mi).

Some people drive that to get to work.

So maybe lose the smug, condescending attitude?
