NASA: We discovered an issue where the rover's calculated position was off by 1mm because of 25 corrupted bits in memory.

@adamshostack NASA: We can autonomously drive virtually unlimited distances over unpaved, rugged terrain and our only limitation is a lack of awareness of our position on the planet.

Tesla: Our "full self driving" cars have full access to GPS and drive on well marked, well-maintained, paved roads, but will randomly accelerate into trees, parked cars, or buildings. *throws up hands*

@mathaetaes To be fair, there are a lot fewer trees, parked cars or buildings on Mars, so there's fewer chances to hit any of them.

@adamshostack True. But there are plenty of big rocks, and I'm sure it would pretty quickly find one.
